Facile fabrication of uniform hollow silica microspheres using a novel biological template

Biological templates, due to their ease of preparation and surface modifications can be a promising approach to fabricate hollow structures. In this study, for the first time, a biological template was used for the production of hollow silica microspheres. Silica was successfully deposited on Staphylococcus aureus cells surface using the Stِber method. The hollow silica spheres with a mesoporous shell of approximately 700 nm in diameter were produced by applying this novel method.
