Abstract
In the present project, two phosphatic/ silk/ nanosilver/ chitosan composites were successfully achieved maintaining the normal ratios between inorganic/organic ratios to be 70/30 mimicking, therefore, natural bone mineral structures.
• Silk fibroin protein and chitosan amide groups acted as organic matrices to provide the active sites available for nucleation and growth ofHA and OCP phases.
• Intimately, the organic matrices m the suitable amount (30%) provided a larger number of active sites, which promoted the self assembly of HA and OCP crystallites on silk fibroin/ chitosan surface in synthesis and in vitro assessment.
• The two developed .composites showed thermal stability up to
200 °C with total weight loss of 6.444 and 8.566 % corresponding to HA and OCP composites respectively. Therefore, assessing the difference in their specific formulae of each with five water molecules for the later.
