Organic electronics at the interface with biology
Prof. George Malliaras

Organic electronics seems to be ideally suited for the interface with biology. The “soft” nature of organic materials offers better mechanical compatibility with tissue than traditional electronic materials, while their natural compatibility with mechanically flexible substrates suits the non-planar form factors often required for bioelectronic implants. More importantly, their ability to conduct ions in addition to electrons and holes opens up a new communication channel with biology. I will review recent progress in the field and subsequently focus on two emerging areas: (a) The development of biosensors using conducting polymer transistors, and in particular their integration with microfluidics to create multi-analyte sensors, and, (b) the development of active substrates for cell growth, in which a potential applied on a conducting polymer substrate controls cell density and morphology.
