Read More »Electrophysiology: Piezos Enable Faster Solution Switching
Electrophysiological studies require fast motions of a double-bore (theta-glass) pipette across cell membranes. With a cell held in a patch clamp and monitored electrically, one bore of the pipette flows a buffer solution, while the other carries a drug or other chemical. By quickly sweeping the pipette so one bore or the other suffuses the cell, its electrophysiological response can be...
