Claim 12:
13. A method for fabricating a filter containing tragacanthin-polyvinyl alcohol (PVA) nanofibers, the method comprising:
obtaining a homogenous tragacanthin-PVA solution by adding tragacanthin to a PVA solution, a concentration of tragacanthin in the homogenous tragacanthin-PVA solution being between 1 w/v % and 1.7 w/v %;
forming a tragacanthin-PVA nanofibrous web on a support layer; and
cross-linking the tragacanthin-PVA nanofibrous web by exposing the tragacanthin-PVA nanofibrous web to a saturated vapor of a cross-linking agent.
