Claim 0:
1. A method for fabricating a filter containing tragacanthin-polyvinyl alcohol (PVA) nanofibers, the method comprising:
obtaining a homogenous tragacanthin-PVA solution by:
obtaining a PVA solution by dissolving PVA in distilled water; and
adding tragacanthin to the PVA solution, a concentration of tragacanthin in the homogenous tragacanthin-PVA solution being between 1 w/v % and 1.7 w/v %;

obtaining a support layer by coating a stainless steel mesh with a thin layer of a hydrophobic polymer; and
forming a tragacanthin-PVA nanofibrous web on the support layer by electrospinning the homogenous tragacanthin-PVA solution onto the support layer.
