as i know not only small molecules, but also big molecules like oil can evaporate (this is also what i experienced in my kitchen). of course evaporation should decrease drastically, with increasing molecular weight. but biomolecules like 200 bp dna may be 200 times bigger that a tri-glyceride molecule. can it still evaporate in very very small quantities? if it does, how can its vapor pressure be calculated? i am a molecular biologist and this is something i experienced through a contamination problem in pcr. the only explanation to my contamination is the evoporation of dna molecules at high temparatures like 95C.
Re: can big molecules like proteins or dna (200bp etc) evaporate?
