Bioactivity of degradable polymer sutures coated with bioactive glass

Journal of Materials Science: Materials in Medicine, 2004
Novel bioactive materials have been prepared by coating violet resorbable Vicryl sutures with a bioactive glass powder derived from a co-precipitation method. Two techniques have been chosen for the composite preparation: pressing the sutures in a bed of glass powder and slurry-dipping of sutures in liquid suspensions of bioactive glass powders.
