15 Years Manufacturer Silk Fibroin Nano/Microspheres Export to The Swiss

Brand Name: Fancci

Alternative Name: Silk fibroin nanoparticles/microparticles

Introduction:

Silk fibroin protein-based micro- and nanospheres provide new options for drug delivery and other applications due to their biocompatibility, biodegradability and tunable drug loading and release properties, especially for protein/peptide drugs and water-insoluble drugs. The high encapsulation efficiency and controllable drug release kinetics can be achieved through control of crystalline beta-sheet content in silk materials.

Our proprietary silk nano/microspheres are fabricated using a one-step, solvent-free method, and are provided as either water suspension or a lyophilized powder, which can be readily re-dissolved in water before use. 

Parameter and properties

Size of nanosphere: can be varied in a range of 100-1000 nanometers;
