They are very simple cells that fall under the heading prokaryotic. You don't usually get infected by dead bacteria, because  They get recycled. Unlike larger organisms, when single-celled organisms die, they usually undergo a process called lysis, in which the cell membrane disintegrates.

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.
