Electron-conducting crosslinked polyaniline-based redox hydrogel, and method of making
A polymer matrix that may coated on an electrode is created by co-crosslinking (1) an adduct of a polyaniline formed by templated oxidative polymerization on a polymer acid; (2) a water-soluble crosslinker; and (3) a redox enzyme. The polymer matrix may be hydrated, and the absorbed water may make it permeable to, for example, glucose.

Nonadherent and superabsorbent wound dressings based on electrospun zwitterionic monomers
A method for creating a non-adhesive, water-absorbent wound dressing includes creating a mixture of monomers, crosslinker, initiator, and solvent, initiating polymerization of the monomers to begin polymerization of the monomers; quenching the polymerization of the monomers when the mixture has a viscosity suitable for electrospinning; electrospinning the polymer mixture to form a fibrous membrane; and thereafter further polymerizing and crosslinking the fibrous membrane. The monomers are chosen from select species and, following this process, provide wound dressings that are nonadherent to a wound so as to be potentially reusable; superabsorbent; non-biofouling.
