Project aim: RealSense2 will use mathematical modeling coupled to experimental validation to develop and optimize sensors for biomass &amp; nutrients/metabolites in media and enable their integration into commercial bioreactors. This will provide better bioprocess control, in-line monitoring and when combined with filtering, can enable media recycling which may reduce overall costs of proliferation steps for cultivated meat production.
&nbsp;
About the project: The specific objectives of the projects are a) to identify the most efficient configuration for integrating sensors into the stirred tank bioreactor through coupled mathematical modeling, computational fluid dynamics (CFD) and experiment, b) to develop and fabricate integration-ready sensors of biomass/nutrient/metabolite sensors ready for integration (TRL5-6) into the bioreactor and to integrate the fabricated sensors into the bioreactor following design identified through the CFD models as the most efficient, and c) to test the bioreactors with integrated sensors using commercially-relevant cell types provided by the advisory members. Importantly, cells of different origin will be tested i.e. mammalian and invertebrate.

THE GOOD FOOD INSTITUTE GRANTS

BioSense participates in a range of pan-European initiatives that aim to centralise environmental data coming from various regions, sources and institutions. Such a database would provide researchers, government institutions and NGOs precious information about the state of ecosystems around Europe along with an insight on how they are changing in time.

&nbsp;

Environmental and ecological data is very heterogeneous. It encompasses logs from sensors, expert observations, photos from smartphones and UAVs, lab analyses and others. Individual data from one source or one region provides little information, as it cannot be analysed in a wider context. Also, data is usually kept at individual institutions separately, which poses further hurdles for comprehensive analysis and directly contradicts the EU principles of open science.

&nbsp;

For these reasons, we participate in a suite of European projects where we are developing a platform for deposition of environmental and ecological data. The platforms facilitates networking between European institutions and a collaborative approach to tackling the problems of climate change, global warming, habitat loss and altered competitive relationships within flora and fauna.

Ecology Platforms

Due to their small diameter (ca. 100 nm) and highly porous nature, mesoporous silica nanoparticles (MSNs) have high specific surface area (ca. 1000 m2/g) which can be utilized for a plethora of functionalizations, loading/adsorption of different molecules and their removal, or as a platform for signaling molecules to detect different analytes.

&nbsp;

Mesoporous organosilicate nanomaterial (also termed Periodic Mesoporous Organosilica (PMO)) contains a large percentage of organic groups within the nanosphere, exhibiting unique characteristics for different applications.

&nbsp;

Our research is being conducted toward design of new series of MSN and PMO nanomaterials, as well as their core/shell analogs.

&nbsp;

Surface of these nanomaterials is being modified with different molecules to specifically interact with desired tissues, pollutants, or analytes, for their efficient application in monitoring and protection of health, food and the environment.

&nbsp;

One of the research goals is to develop smart nanomaterials with stimuli-responsive release of MSN/PMO-loaded molecules for diagnostics, imaging, and therapy of cancer tissues.

&nbsp;

Polymer-MSN composite materials are also being developed for applications as antimicrobial smart food packaging and medical implants.

&nbsp;

Finally, PMO nanoparticles are being constructed for efficient UVA and UVB blocking and application in a safer generation of sunscreens.

Silica nanomaterials

Biosensors are analytical devices for detection of the biologic material which may include biomolecules, biological structures or microorganisms (bacteria, viruses, algae, spores). Nowadays, they are being used for food safety evaluation, environmental monitoring, or for early detection of infectious diseases in biomedicine.

&nbsp;

We work on the development of new point-of-need biosensor transducers, biofunctionalization of the sensors with bioreceptors, and sensor integration into microfluidic systems. Developed biosensors are being implemented for detection of bacteria in food and water, detection of cyanobacterial toxins produced during harmful algal blooms, as well as for a fast detection of faecal bacteria and other microbiological pathogens in water.

&nbsp;

More concrete, we focus our research on development of new nanomaterials for functionalization of the biosensor electrodes and fabrication of new electrochemical transducers using different fabrication technologies. Particular attention is dedicated to new materials which will enable selective and efficient binding of the analytes and to the novel biosensor designs to increase the selectivity, sensitivity and limit of detection. Therefore, we develop the novel methods of graphene modification, and the mask-less methods of graphene patterning and integration to conventional industrial routes.

&nbsp;

A special focus is placed on biosensors containing enzymes, antibodies and nucleic acids (DNA, RNA) as recognition elements. This research is performed in close collaboration with the Center for Biosystems in which experts work on biomolecular engineering and molecular detection methods including the cutting-edge isothermal methods for nucleic acid amplification such as LAMP (loop-mediated isothermal amplification) and RPA (recombinase polymerase amplification) and other ways of molecular detection which can be well combined with the biosensing methods.

&nbsp;

In addition, BioSense Institute works on the new types of biosensors for monitoring nutrients and products of cellular metabolism during cultured meat production, as another example of excellent multidisciplinary collaboration with the Center for BioSystems and the researchers working on Cellular agriculture topics.

Biosensors

Cellular agriculture refers to production of agricultural products using cell cultures. Cellular agriculture products are part of the larger group called Alternative proteins (alt.pro). Alt.pro are proteins that can act as substitutes for traditional animal‐based food. Generally, alt.pro are classified based on the source into: Plant-based, Insect-based and Cultured meat that is produced by cellular agriculture methods. Majority of the methods for cellular agriculture stem from the tissue engineering and biomedical field, while the application of the products generated by cellular agriculture falls predominantly into the food science.

&nbsp;

Cultured meat is the main type of alternative proteins BioSense addresses. One of the main challenges for scaling up the cultured meat production to the industry levels is concerning the overall costs of production. The highest portion of costs (up to 80%) for cultured meat production is for the cell culture medium and fetal calf or bovine serum. The challenge to decrease expenses is not only in designing low-cost cell culture medium formulations, but also in developing methods to optimize the bioreactor design, instrumentation and to include monitoring features via sensors for the maximum cell production capacity per unit medium volume.

&nbsp;

In that sense, we focus our research on optimizing procedures for generating cellular products, and we closely collaborate with the Center for sensing technologies regarding development of sensors for monitoring of key parameters in cultured meat bioprocess: Biomass concentration, a key variable in cell cultures and Concentration of key nutrients – glucose and glutamine and their main metabolites, lactate and ammonia, that can inhibit the cell growth. Sensors are tested using "miniaturized" bioreactors i.e. microfluidic model and Lab-on-a-chip (LOC) principle, which will be scaled up to the bioreactors of larger volumes.

GRANTOVI INSTITUTA DOBRE HRANE

Ćelijska poljoprivreda se bavi proizvodnjom poljoprivrednih proizvoda pomoću kultura ćelija i ulazi u oblast tzv. alternativnih proteina (alt.pro). Alt. pro su proteini koji se mogu koristiti kao zamena za uobičajene životinjske proteine. Alt.pro mogu biti biljnog porekla, mogu biti i od insekata, a posebna grupa proteina označena kao kultivisano meso se dobija pomoću metoda ćelijske poljoprivrede. Većina metoda ćelijske poljoprivrede potiče iz biomedicine i tkivnog inženjerstva, dok primene i upotreba proizvoda dobijenih ćelijskom poljoprivredom pretežno pripadaju oblasti tehnologije hrane.

&nbsp;

Kultivisano meso je osnovni tip alternativnih proteina kojim se bavi Institut BioSens. Jedan od glavnih izazova za skaliranje tj. industrijsku proizvodnju kultivisanog mesa su ukupni troškovi proizvodnje. Najveći deo troškova (čak do 80%) za kultivaciju mesa potiče od cene hranljivog medijuma i fetalnog goveđeg seruma, neophodnih za gajenje ćelija u kulturi. Troškovi se mogu smanjiti ne samo jeftinijim formulacijama hranljivog seruma, već i putem metoda optimizacije dizajna bioreaktora i instrumenata i naročito upotrebom senzorskog sistema praćenja ključnih parametara, da bi se postigla maksimalna produkcija ćelija po jedinici zapremine medijuma.

&nbsp;

U tom smislu se fokusiramo na optimizaciju procedura za dobijanje ćelijskih produkata, a u bliskoj saradnji sa Centrom za senzorske tehnologije razvijamo i senzore za praćenje ključnih parametara u bioprocesu kultivacije mesa: koncentracija biomase, što je osnovni parametar ćelijske kulture i koncentracija osnovnih hranljivih materija – glukoze i glutamina i njihovih glavnih metabolita, laktata i amonijaka, koji mogu inhibirati rast ćelija. Senzori se testiraju na „minijaturizovanim“ bioreaktorima tj. mikrofluidnim modelima uz primenu „Laboratorija na čipu“ principa, koji će se zatim skalirati na bioreaktore većih zapremina.

Ćelijska poljoprivreda

Biosenzori su analitički uređaji koji služe za detekciju biološkog materijala kao što su biomolekuli, biološke strukture ili mikroorganizmi (bakterije, virusi, alge, spore). Široku primenu biosenzori nalaze u kontroli bezbednosti hrane, monitoringu životne sredine, kao i u ranom otkrivanju infektivnih bolesti u biomedicini.

&nbsp;

Naša istraživanja su usmerena na razvoj novih biosenzorskih transdjusera, biofunkcionalizaciju senzora sa bioreceptorima, i integraciju senzora u mikrofluidične sisteme. Razvijeni senzori se koriste za detekciju bakterija u hrani i vodi, za detekciju cijano toksina nastalih tokom cvetanja algi, kao i za brzu detekciju fekalnih bakterija i drugih mikrobioloških patogena u vodi.

&nbsp;

Bavimo se i razvojem novih nanomaterijala za funkcionalizaciju biosenzorskih elektroda i fabrikaciju novih elektrohemijskih biosenzora koristeći različite tehnologije fabrikacije. Deo istraživanja je usmeren na nove materijale koji će omogućiti selektivno i efikasno vezivanje analita, kao i na projektovanje biosenzora u cilju poboljšanja njihove selektivnosti, osetljivosti i limita detekcije. Bavimo se i novim metodama modifikacije grafena, novim metodama za njegovu sintezu i integraciju u konvencionalne industrijske procese.

&nbsp;

Posebna pažnja je posvećena biosenzorima na bazi enzima, antitela i nukleinskih kiselina (DNK, RNK). Ova istraživanja se izvode u bliskoj saradnji sa Centrom za biosisteme u kojem istraživači rade na metodama biomolekularnog inženjerstva i molekularne dijagnostike što uključuje i najsavremenije izotermalne metode za umnožavanje nukleinskih kiselina kao što su LAMP (Loop Mediated Isothermal Amplification) i RPA (Recombinase Polymerase Amplification) koje se mogu dobro kombinovati sa biosenzorima razvijenim u okviru Centra za senzorske tehnologije.

&nbsp;

Takođe, Institut BioSens radi na novim vrstama biosenzora za monitoring hranljivih materija i produkata metabolizma ćelija u procesu proizvodnje kultivisanog mesa, što je još jedan primer dobre multidisciplinarne saradnje sa Centrom za biosisteme i istraživačima koji rade u okviru oblasti ćelijske poljoprivrede.

Biosenzori

BioSens učestvuje u raznim panevropskim inicijativama kojima je cilj da centralizuju podatke o životnoj sredini koji dolaze iz različitih regiona, izvora i institucija. Takva baza podataka pružila bi istraživačima, vladinim institucijama i nevladinim organizacijama dragocene informacije o stanju ekosistema širom Evrope, kao i uvid u to kako se oni vremenom menjaju.

&nbsp;

Ekološki podaci su vrlo heterogeni. Obuhvataju zapise sa senzora, stručna zapažanja, fotografije sa pametnih telefona i dronova, laboratorijske analize i druge. Pojedinačni podaci iz jednog izvora ili jednog regiona pružaju malo informacija, jer se ne mogu analizirati u širem kontekstu. Takođe, podaci se obično čuvaju u pojedinačnim institucijama odvojeno, što predstavlja dodatne prepreke za sveobuhvatnu analizu i direktno je u suprotnosti sa principima otvorene nauke EU.

&nbsp;

Iz tih razloga učestvujemo u nizu evropskih projekata gde razvijamo platformu za čuvanje podataka o životnoj sredini i ekologiji. Platforme olakšavaju umrežavanje između evropskih institucija i zajednički pristup rešavanju problema klimatskih promena, globalnog zagrevanja, gubitka staništa i izmenjenih odnosa unutar flore i faune.

Ekološke platforme

Zbog malog prečnika (oko 100 nm) i veoma porozne prirode, mezoporozne silikatne nanočestice (MSN) imaju veliku specifičnu površinu (oko 1000 m2 / g) koja se može koristiti za različite funkcionalizacije, punjenje/adsorpciju različitih molekula i njihovo uklanjanje, ili kao platforma za signalne molekule za detekciju različitih analita.

&nbsp;

Mezoporozni organosilikatni nanomaterijal (Periodični mezoporozni organosilikat (PMO)) sadrži veliki procenat organskih grupa, što omogućuje da ispoljavaju jedinstvene karakteristike za različite primene.

&nbsp;

Naše istraživanje se provodi u cilju dizajniranja novih serija MSN i PMO nanomaterijala, kao i njihovih jezgro / ljuska analoga.

Površina ovih nanomaterijala se modifikuje različitim molekulima kako bi specifično stupila u interakciju sa željenim tkivima, zagađivačima ili analitima, radi njihove efikasne primene u praćenju i zaštiti zdravlja, hrane i životne sredine.

&nbsp;

Jedan od ciljeva istraživanja je razvoj pametnih nanomaterijala sa stimulans-responzivnim oslobađanjem molekula iz MSN / PMO materijala, sa primenom u dijagnostici, snimanju i terapiji tkiva raka.
Kompozitni materijali polimer-MSN se takođe razvijaju u cilju primene kao antimikrobnih pametnih ambalaža za hranu i medicinskih implanata.

Konačno, nove PMO nanočestice se konstruišu radi efikasnog blokiranja UVA i UVB zračenja i primene u bezbednijoj generaciji krema za sunčanje.
