Light-induced replication of nanobacteria: a preliminary report.

Objective: The purpose of the present study was to investigate the effect of light on nanobacteria.

Background Data: Since their first description in literature, it is not clear whether the nanoparticles called "nanobacteria" are alive or not. The 80-1,000-nm-sized spherical particles are protected by a crystalline carbonate apatite shell and are culturable in cell culture media.
