Portable cell-based biosensor system for toxin detection
(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 ...
Cell based biosensors using microelectrodes
(Stanford University, 1998-11)
Instruments for the study of living cells have historically been of significant
importance for such things as basic neuroscience and cell biology. More recent work has included extending the use of cell based sensors to ...
Description and demonstration of a CMOS amplifier-based-system with measurement and stimulation capability for bioelectrical signal transduction
(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 ...
Cell-based sensor microelectrode array characterized by imaging x-ray photoelectron spectroscopy, scanning electron microscopy, impedance measurements, and extracellular recordings
(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 ...
