Abstract
We have fabricated a microfluidic device comprising a 100 pL scale analytical chamber for electrochemical measurement of cellular activities. The microfluidic main channel and the analytical chamber were fabricated using poly(dimethylsiloxane) (PDMS). The chamber contained two Pt microelectrodes served as an electrochemical working electrode and an electrophoretic electrode to manipulate cells into the chamber. Yeast cells were introduced to the chamber by the electrophoresis, and its β-galactosidase (βGal) activities were characterized by amperometry. p-Aminophenol (PAP), generated by the enzyme-catalyzed hydrolysis of p-aminophenyl-β-D-galactopyranoside (PAPG), was detected electrochemically.
