Microorganisms and organic preservation?

... you want but, did you try simply change the water for organic solvent that will evaporate? Fix the fruit with protein linking fixative like 2% paraformaldehyde or glutaraldehyde for several days. Put the fixed fruit into serie of organic solvent concentration gradient- 30% ethanol, 50% ethanol, ...

Re: Electrophoresis of ionic complexes

... However, it might be a good idea to try. As you may have guessed, this siRNA-polymer complex is for physiological use, so I'm not sure how paraformaldehyde would effect cytotoxicity, efficacy, and how easily the siRNA would dissociate in the body. Do you happen to suggest any papers that ...
