Electronic Sensing Group
About
The „Electronic sensing “ group is working on the development of innovative semiconductor field-effect transistor (FET) structures and ultra-high sensitivity resonators for characterization of biological liquids and cellular dynamic processes. We are fabricating advanced nanowire FET (NW FET) and graphene FET (GFET) biosensors as well as micro/nano fluidic channels using state of the art Helmholtz Nano Facility. To develop a high-performance liquid gated (LG) FET biosensor, an increased focus on the quality of interfaces in the LG NW FET structures is crucial for analysis of dynamic processes in biological liquids. Valuable signals can be obtained from the dynamic processes of ions and charged molecules at the liquid-solid interface.
In the field of semiconductor FET devices, noise spectroscopy is a powerful and effective characterization method. Noise spectroscopy results provide a unique opportunity to enhance the sensitivity of biosensors and help to improve our understanding of biological processes, even at the molecular level. About 300% sensitivity enhancement can be obtained in biosensors using single trap phenomena resulting in two-level random telegraph signal switching in current. In addition, the biosensitivity in liquid-gated devices can be enhanced because the parameters of single-trap and interface phenomena can be effectively adjusted by light. Advanced GFET biosensors allow to study ischemia and reperfusion states in a network of cardiomyocytes as a part of real-state conditions of heart injuries and inflammations, specifically myocardial infractions. The action potentials recorded with the LG GFETs, especially their shape, and duration of the active segment in measured extracellular action potentials, can be used to characterize the real state of cells provide prospects for building the next generation of ultrasensitive biosensors.
A new approach involving a multifrequency single resonator operation on 6 modes with a microfluidic chip demonstrates high sensitivity in analyses of amino acids in solutions and opens prospects for studies of bioliquids in human body using contactless microwave technique.
