Electrostatic Force Microscopy Study of Open-Circuit Photovoltage from a bR/ITO Heterostructure

Crittenden S., Hillebrecht J., Howell S., Birge R.R., Reifenberger R., Purdue University, US

Bioelectronics offers a potential alternative to Si-based technology because natural evolution and selection have optimized many biological molecules to perform tasks that can only be mimicked by complicated electronic circuits. Purple membrane (PM) patches containing [...]

Towards Color Sensitivity of Protein Based Artificial Retina

Lensu L., Frydrych M., Aschi C., Parkkinen J., Parkkinen S., Parkkinen J., Parkkinen S., Jaaskelainen T., Lappeenranta Univeristy of Technology, FI

Bacteriorhodopsin (BR) has been studied as a material for molecular electronics applications. Thin film elements based on BR and its variants in polyvinylalcohol (PVA) have been produced to determine the photoelectrical properties of the material [...]

Model of Photovoltage Response of Bacteriorhodopsin in PVA Films

Frydrych M., Lensu L., Aschi C., Parkkinen J., Parkkinen S., Parkkinen J., Parkkinen S., Jaaskelainen T., Lappeenranta University of Technology, FI

Bacteriorhodopsin (BR) is a light-transducing protein contained in a purple membrane of microorganism Halobacterium salinarium. Natural function of BR is to act as a light-driven proton pump in energy balancing mechanism of the bacterium. Numerous [...]
