Abstract
A method for making a water insouble bicompatible gel includes activating HA with an activating agent to form activated HA, and reacting the activated HA with a nucleophile, under conditions producing the water insoluble bicompatible gel. Also, a method for making a water insoluble biocompatible film includes providing a biocompatible gel made according to the above method, and drying the gel or compressing the gel under conditions permitting escape of water from the gel. Also, a water insoluble composition including HA is prepared without the use of any bifunctional or polyfunctional nucleophile.
