Try out the University of Tennessee, Professor Michael Sepaniak. He did some
work on "Chiral and Achiral Biosensing using Nanostructured
microcantilevers".

<[ Hello there
<[
<[ I have a few basic bioMEMS queries. A device of mine has an array of
<[ cantilevers with one side of each coated with biomolecules
<[ (antibodies).
<[
<[ *How do I coat different cantilevers with different
<[ antibodies? ( I donot
<[ want antibodies for cantilever A to get onto cantilever B)
<[
<[ *what is a micro/nano pipette? (Do I need it for the above qn?)
<[
<[ *I am doing a test of antigens in blood. So what I have is a
<[ chamber with
<[ my cantilever(s) and serum floating about. Say the blood does have a
<[ particular qty of antigens and it does get stuck to the antibodies
<[ specific to it on the cantilever. Thus there is a deflection which I
<[ measure and hence I know how many molecules got stuck to the
<[ cantilever
<[ (can someone also elaborate on how i do this). Now how do I
<[ relate the
<[ concentration of the antigens in the serum to that on my
<[ cantilever? Is it
<[ probabilistic? Or do I have to aim a fixed qty of serum only on the
<[ cantilever so that every (?) molecule gets stuck????
<[
<[ Plz help me out.
<[
<[ Thanks a million
