Re: [DIYbio] Surface Plasmon Resonance

Definitely interested. I'm wondering what sensor you were showing in
your images?

I've been studying low-noise design for high-noise environments such
as electron microscopes and quantitative analysis with various things
like spectrophotometry, potentiometry, voltammetry, electroporation,
x-ray spectroscopy and all the other noisy radio stuff in the
environment. It's always interesting to see new sensors!

If I can be of any help, let me know. I've got a few of these printed
circuit boards but haven't tried assembling them yet:
