Abstract
A microcantilever modified with a layer of acetyl cholinesterase (AChE) responding to paraoxon is reported in this work. Acetyl cholinesterase was immobilized on a microcantilever through a cross linker to a monolayer on gold surface of the microcantilever. The microcantilever underwent a maximum of 7 nm bending due to the inhibition of AChE by paraoxon that slightly changed the conformation of AChE.
