__1/22/08__ - Today, because there was no school, I went to the lab at Notre Dame early, at 1:00 in the afternoon. For the first few hours I spent my time making new samples, and these were what I made...

1.) Plain Silicon Sample

2.) Silicon Samples with APTES monolayer

3.) Silicon w/ APTES, and linearized DNA (different concentration).

4.) Mica with DNA on it, but no magnesium adhesive layer (so no DNA shoudl stick). This was mostly a control experiment.

__1/24/08__ - Today I went to the Notre Dame lab during Science Research class. I used the AFM today and looked at a plain silicon sample, but I found, under the microscope, that it was quite dirty. In fact, too dirty to serve any comparative value. I also looked at some mica samples, this time with DNA plus a magnesium adhesive. Before, I looked at the same kind of sample, but with no magnesium and found no DNA. This time I did find some linearized plasmids in a few images, and they came out rather good.
