Microgrooved collagen-based corneal scaffold for promoting collective cell migration and antifibrosis.

Collagen is a promising material for corneal tissue engineering. The surface topography of collagen is critical for cornea reconstruction and regeneration. Herein, we fabricated collagen films with microgrooved surface to investigate the effect of collagen film topography on corneal cell migration and antifibrosis.

Functionalization of composite bacterial cellulose with C nanoparticles for wound dressing and cancer therapy.

A series of novel bacterial cellulose/C (BCC) composites was prepared using a original dehydration-rehydration method. The composites were characterized to demonstrate their potential in multifunctional wound dressings for skin cancer treatment using photodynamic therapy. Raman spectroscopy revealed that the C nanoparticles were successfully incorporated into the bacterial cellulose (BC) network.
