A technique to enhance electrochemical signals and shorten response time by manipulating yeast near the sensing electrode

In this work, we manipulated recombinant yeast cells onto a sensing electrode by using hydraulic and electrophoretic force; and thus the current response of trace enzyme activity was increased in p-aminophenyl- • •-D-galactopyranoside (PAPG) solution. The recombinant yeast which can generate • •̲-galactosidase (• •̲-Gal) in response to steroidal hormone 17… CONTINUE READING
