Antimicrobial starch-citrate hydrogel for potential applications as drug delivery carriers

Antimicrobial starch-citrate hydrogels were prepared by physical crosslinking of starch citrate, Poly(vinyl alcohol (PVA) and Polyethylene glycol (PEG) via the freeze–thaw technique. This starch-citrate hydrogel exhibited excellent antimicrobial activity against various bacteria strains such as Escherichia coli (gram negative), Staphylococcus pyogenes (gram negative), Salmonella thypimurium (gram positive) and Streptococcus aureus (gram...
