Abstract

This paper proposes a new method for generating microcarries from bacterial cellulose (BC). BC, which is produced by specific bacteria, is a hydrogel composed of a three dimensional network structure formed by cellulose nanofibers. BC as an ECM-like nanofibrous material exhibits an excellent environment for cellular adhesion. Moreover, BC has a high biocompatibility and mechanical strength. From these properties, BC is expected to be applied for microcarriers, which is used for cultivating anchorage-dependent cells. Then, we developed a microfabrication process to create BC microcarriers by using gelatin microspheres as sacrificial architectures. In addition, the monodispersity of the formed BC microcarreirs was investigated.
