## I'm keeping this trial dilute just to see if this stuff lays down on the surface or not. | |||

## This trial looks like I might have had too high of a concentration. I may decrease it for the next run, but I want to see what the surface looks like first. | |||

ZIF-8 on Silicon 100The NIST crew have asked me to try and grow some MOF or ZIF on a Si chip. Nikolai Klimov made some chips that have been coated in PMMA except for a small window that has exposed Si. It seems like the best way to do this will be to put down a monolayer of silane down on the Si first. However, I'm going to try some brute force methods first.
