A novel flexible electrochemical biosensor for protein biomarker detection was successfully designed and fabricated on a nanoporous polyimide membrane using zinc oxide (ZnO). Nanostructures of ZnO were grown on microelectrode platform using aqueous solution bath. Electrochemical measurements were performed using gold, ZnO seed and nanostructured electrodes to study the influence of electrode surface area on biosensing performance. Feasibility analysis of sensor platforms was evaluated using high concentrations (in ng/mL) of troponin-T. The results showed that improved performance can be obtained on nanostructured platform by careful optimization of growth conditions. This study demonstrates the development of nanostructured ZnO flexible biosensors towards ultra-sensitive protein biosensing.

Improved Performance

Bulk heterojunction photovolataic devices based on blends of conjugated polymer poly (2- methoxyl-5- dodecoxyl p-phenyl vinylene) (PMODOPV) as electron donor and crystalline ZnO nanowires as electron acceptor have been studied. We show that photovoltaic devices using zinc oxide nanowires overlaid with conjugated polymers give improved performance compared with devices made only from polymer. The improvement is consistent with improved electron transport perpendicular to the plane of the film. Solar power conversion efficiency of 1.37% were achieved under AM1.5 illumination .

For further uptake in the solar cell industry, n-ZnO/p-Si single heterojunction solar cell has attracted much attention of the research community in recent years. This paper reports the influence of bandgap and/or electron affinity tuning of zinc oxide on the performance of n-ZnO/p-Si single heterojunction photovoltaic cell using PC1D simulations. The simulation results reveal that the open circuit voltage and fill factor can be improved significantly by optimizing valence-band and conduction-band off-sets by engineering the bandgap and electron affinity of zinc oxide. An overall conversion efficiency of more than 20.3% can be achieved without additional cost or any change in device structure. It has been found that the improvement in efficiency is mainly due to reduction in conduction band offset that has a significant influence on minority carrier current.
