Fabrication of Micro-Patterned Calcium Carbonate Materials Through Template-Assisted Microbially Induced Calcium Carbonate Precipitation

Abstract

In this study, we report an approach for fabricating micro-patterned calcium carbonate materials. The approach is based on template-assisted microbially induced calcium carbonate precipitation, and is green and eco-friendly. As a proof of concept, by varying the templates and optimizing fabrication parameters, different patterned calcium carbonate materials were obtained. Materials with periodic patterns were also fabricated through a periodic template, showing a good scalability of this approach. The results of this study have a great potential in various applications, for example, in the fabrication of coating materials and bone-regeneration materials, where patterned calcium carbonate films with controlled morphologies are highly in demand.
