Abstract
Biological specimen recovery materials include cellulose acetate nanofibers that are capable of dissolution upon contact with a liquid comprising a dissolution effective amount (e.g., between about 1 to about 10M) guanidinium isothiocyanate (GITC). Kits containing the materials (e.g., in the form of a swab, filtration media or surface wipe) and a dissolution liquid containing the dissolution effective amount of guanidinium isothiocyanate (GITC) are also provided.
