Preparation and characterization of novel silica-butyrylchitosan hybrid biomaterials.
Novel silica-butyrylchitosan hybrid biomaterials were produced by a sol-gel technique, using butyrylchitosan as the organic species incorporated into the silicon alkoxide (TEOS) based network. 3-acryloxypropyl trimethoxysilane (MPTMS) was used effectively to combine the organic and inorganic species to form uniform hybrid biomaterials. All the samples made were in the form of thin, flexible films with transparent clarity. The blood-clotting and platelet adhesion assay confirmed that these hybrid biomaterials displayed potential good blood compatibility.
