Summary in Hungarian
A kutatás összefoglalója, célkitűzései szakemberek számára
Itt írja le a kutatás fő célkitűzéseit a témában jártas szakember számára.
The target is a new energy autonomous system based on micro (photo)electrochemical sensors, for concentration measurement of different ionic species in natural water sources.
It focuses on 3 directions: 1) new materials with high efficiency in solar energy harvesting and fabrication of small ultra-thin solar cells together; 2) new microsensors and materials for detection of nitrites/ nitrates and heavy metals in water; 3) low cost autonomous energy system integration and fabrication.
The microsensors for nitrates/nitrites and heavy metals will be of (photo)electrochemical type. A biosensor based on sensing protein molecules, flagellar filaments with specificity to heavy metals will be integrated.
The studied materials will be SnO2, TiO2 and ZnO. The thin films will be prepared by a broad variety of deposition techniques (sol-gel, spray pyrolysis, magnetron sputtering, hydrothermal synthesis) and will have different morphologies (nanowires, nanotubes, spheres) allowing to select the best sensitivity and selectivity for the sensor. Bacterial flagellar filaments (special protein molecules) will be investigated and engineered as sensitive biolayer for heavy metal detection.
The goals of the project are to develop an integrated materials – technology – product – system concept, demonstrator and prototype for eliminating or minimising the use of chemical batteries, other energy sources, or complex wiring in microsensors/microsystems, increasing the autonomy of sensors, systems and networks, to provide affordable energy technologies with low CO2 emissions and to deliver a portable, autonomous apparatus for water monitoring (detection of nitrates/ nitrides, heavy metals).

- Low cost sensors for fast detection of nitrites/ nitrates and heavy metal
The sensing unit will be developed following the same concept of avoiding critical materials or using them at traces level (dopants) and for specific components.
Platinum and doped tin oxide, both deposited with a polymeric membrane will be used as a sensing element (nitrates/nitrites, heavy metals). In, F and Sb will be tested as dopants for the SnO2 layer. Conducting polymers (PANI, PVC and other polymers) will be used as the membrane sensing layer. The auxiliary electrode, reference electrode and working electrode will be integrated on the same silicon chip. The new disposable biosensor for heavy metals detection will use sensing protein molecules, flagellar filaments with large sensing area.
- Enhancement of the material properties by new preparation methods using doping and different morphologies controlled through chemical methods. The use of more synthesis techniques will allow to select the optimum building-blocks, in terms of output (efficiency) and cost-effectiveness.
- High efficiency solar energy harvester
Optimizing the semiconducting layers required for solar cell manufacturing, especially by rigorous control of doping level will be a valid argument for increasing of conversion efficiency. The main threshold properties will be: (a) Interface compatibility of the single-materials in the multi-materials (2D and 3D nano-composites); (b) thermodynamic compatibility (band gaps alignment). The main considerations are applied for (photo)electrochemical sensors.
- Energy autonomous monitoring system (Prototype) - portable, low cost, easy handling, immediate detection

Final report

  
Results in Hungarian
Kifejlesztettünk új, erősen Ni- és As-kötési képességű fehérjéket . Kifejlesztettünk javitott fehérje termelési protokollokat, és funkcionalizált speciális érzékelőket. Sok kísérletet végeztünk kovalensen rögzített fehérje rétegekkel arany felületen, és megvizsgáltuk ezeket a fém-ion-kötési tulajdonságokat optikai (spektroszkópikus Ellipszometriával) és elektrokémiai (ciklikus voltametria ) módszerekkel. Az előállitott érzékelőket szállítani lehet normál postai úton is a partnereknek, és eltárolhatóak a hűtőszekrényben több mint 6 hónapig a végső használatig. Ígéretes elektrokémiai méréseket végeztünk ezeken az új típusú érzékelő csipekkal. A mérések bebizonyították, hogy a fehérjealapú érzékelő rétegek stabilitása elég jó, és az érzékelő chipek újra felhasználhatók kémiai tisztítás után is akár 2-3 hónappal. Ez a vizsgálat bizonyítja, hogy az előkészített chipek több hónap után és többször is felhasználhatóak. További információk: http://www.icf.ro/pr_2016/WaterSafe/Obtained_results.html
Results in English
We developed new proteins with strong Ni- and As-binding capability. The protein production protocols were improved, and functionalized special sensors were developed. We performed several experiments to fabricate covalently immobilized protein filament layer on gold surface and investigated the developed metal-ion-bonding (Ni, As) proteins by optical (Spectroscopic Ellipsometry) and electrochemical (Cyclic Voltammetry) methods The produced sensors can be delivered by normal mail to partners and stored in fridge for more than 6 months for final using. Promising electrochemical measurements were performed with these new types of sensor-chips. The measurements proved that the stability of proteinous sensing layer is good enough and the sensor chips can be re-used even after 2-3 month and chemical cleaning. This later investigation series prove that the prepared chips can be used after several months and more than once. More results: http://www.icf.ro/pr_2016/WaterSafe/Obtained_results.html
