So, thought I should share a funny story. I just started my second year of grad school and I've been working in my lab for just a few weeks.
I have been having a huge issue with my project. I'm doing photolithography to make microchannels to separate biomolecules by differing potentials. The wafers keep coming out too bad to actually work with. So sciencey words aside, I FINALLY actually look at the bottle of photoresist and it expired two months ago.
Moral of story- always check expiration dates.
But, the wafers look super neat with all their bubbles.
