Abstract

An individual cyanobacterium cell is interfaced with a nanoporous biohybrid layer within a mesoporous silica layer. The bio-interface acts as an egg membrane for cell protection and growth of outer shell. The resulting bilayer shell provides efficient functions to create a single cell photosynthetic bioreactor with high stability, reusability, and activity.

Keywords: biointerfaces; bioreactors; cell stability; cell surface functionalization; encapsulation; photosynthetic cells.
