Hello forum,

I'm a applied physics student doing a project for school.

The goal is to detect 1-10 ppm of acetone in the air. The way this is supposed to be done is via a thin Teflon film on a micro ring resonator.
the gold particles are supposed to increase the sensitivity. How it all works is not important.

my question is, how would i go about getting a thin(1 micrometer) Teflon layer embedded with gold nanoparticles?

thanks in advance for your reaction'

Here's an example of a technical not from Sigma-Aldric on a similar topic:  http://www.chemicalforums.com/index.php?topic=68688.msg247767#msg247767  If you search around, you can find others there.  You can also have these app notes mailed to you-- its a way for Sigma Aldrich to advertise their precursors.
