Dielectrophoretic immobilisation of antibodies on microelectrode arrays

Lab on a Chip, 2014
A silicon based chip device with a regular array of more than 100,000 cylindrical sub-microelectrodes has been developed for the dielectrophoretic (DEP) manipulation of nanoparticles and molecules in solution. It was fabricated by a standard CMOS (complementary metal oxide semiconductor) compatible process.

Evaluation of the stability of intracortical microelectrode arrays

IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2006
In order to use recorded neural activities from the brain as control signals for neuroprosthesis devices, it is important to maintain a stable interface between chronically implanted microelectrodes and neural tissue. Our previous paper introduced a method to quantify the stability of the recording microelectrodes.
