Abstract

The present invention provides silk fibroin micro-particles having a high crystallinity index (1.3-1.5) and low sphericity index (≤0.01) and a process for the preparation thereof. The high crystallinity index confers longer degradation periods to the instant silk fibroin micro-particles, therefore facilitating their use in biomedical applications.
