Research Conducted at Taras Shevchenko National University Has Provided New Information about Biosensing (Sensitivity Enhancement of Si Nanowire Field Effect Transistor Biosensors Using Single Trap Phenomena)

By a News Reporter-Staff News Editor at Biotech Week -- Data detailed on Biosensing have been presented. According to news originating from Kiev, Ukraine, by NewsRx correspondents, research stated, "Trapping-detrapping processes in nanostructures are generally considered to be destabilizing factors."

Our news journalists obtained a quote from the research from Taras Shevchenko National University, "However, we discovered a positive role for a single trap in the registration and transformation of useful signal. We use switching kinetics of current fluctuations generated by a single trap in the dielectric of liquid-gated nanowire field effect transistors (FETs) as a basic principle for a novel highly sensitive approach to monitor the gate surface potential."

According to the news editors, the research concluded: "An increase in Si nanowire FET sensitivity of 400% was demonstrated."
