Cell-based sensor microelectrode array characterized by imaging x-ray photoelectron spectroscopy, scanning electron microscopy, impedance measurements, and extracellular recordings
Jung, D.; Cuttino, David; Pancrazio, Joseph; Manos, Patricia; Cluster, T.; Sathanoori, R.; Aloi, L.; Coulombe, M.; Czarnaski, M.; Borkholder, David; Kovacs, Gregory; Bey, Paul Jr.; Stenger, David; Hickman, J. (American Vacuum Society, 1998-05)We are developing a cell-based biosensor consisting of a planar microelectrode array that allows detection of extracellular potentials and their modulation in the presence of toxins or other active agents. To improve ... -
Description and demonstration of a CMOS amplifier-based-system with measurement and stimulation capability for bioelectrical signal transduction
Pancrazio, Joseph; Bey, Paul Jr.; Loloee, Arash; Manne, SubbaRao; Chao, Hui-Chuan; Howard, Lorn; Gosney, W. Milton; Borkholder, David; Kovacs, Gregory; Manos, Patricia; Cuttino, David; Stenger, David (Elsevier www.elsevier.com/locate/bios, 1998-10)An extracellular recording system incorporating an electrode array and an amplifier/stimulator CMOS chip is described and characterized. Important features of this custom VLSI chip include 16 instrumentation amplifiers ... -
Microelectrode arrays for stimulation of neural slice preparations
Borkholder, David; Bao, J.; Maluf, Nadim; Perl, E.R.; Kovacs, Gregory (Elsevier, 1997-11)A planar 6 x 6 array of iridium electrodes with four reference electrodes has been developed for use with neural tissue preparations. Precise knowledge of the relative locations of the array elements allows for spatial ... -
Portable cell-based biosensor system for toxin detection
Pancrazio, Joseph; Bey, Paul Jr.; Cuttino, David; Kusel, Julian; Borkholder, David; Shaffer, Kara; Kovacs, Gregory; Stenger, David (Elsevier www.elsevier.com/locate/sensorb, 1998-12)A portable cell-based biosensor has been developed and characterized. The prototype system relies on extracellular recording from excitable cells cultured over an array of platinized gold microelectrodes. Extracellular ...
