Molecular Bioelectronics Group

About

The Molecular Bioelectronics Group is working on development of electrochemical biosensors utilising specific target molecular bindings.

We develop several novel biosensors concepts that are based on the detection of changes of the solid/liquid interface impedance caused by aptamer/target binding events by utilizing liquid gate FETs, micro-fabricated or printed microelectrodes, and conventional electrochemical setups.

Molecular Bioelectronics : We develop single molecules and ensemble bio-electronic devices for the investigation and control of charge transport phenomena in and across biomolecules. These devices are operated at ambient conditions, in vacuum, and in liquids. The gained knowledge provides the basis for designing novel electronic devices and advancing electrochemical biosensors.

Aptamer sensors: DNA aptamer molecules can be utilized as receptor layer and substitute antibodies in modern biosensors. We develop new electrochemical aptamer sensors for reliable point of care detection of various biomarkers. Furthermore we aim to advance current receptor immobilization and signal amplification methods to enhance the sensor performance.

Nanostructured cell interfaces: Using large area nanoparticle pattern and 3D nanostructured substrates, we systematically screen the interactions between cell and solid surfaces with respect to the spatial dimensions such as size, distance, and pitch. Special attention is given to cell’s contact with the surfaces and how these surfaces can influence the neuron development and neurites orientation
