First Observation of Crystallike Configuration of Microorganisms in an RF Plasma

A crystallike structure was successfully formed as a result of the levitation of a kind of bacillus microorganisms Klebsiella pneumoniae in a radio frequency (RF) plasma. The crystallike structure was confirmed to be hexagonal from top-view photograph. Neutral gas friction cools the particles down to equilibrium positions. Field Emission Scanning Electron Microscope (FE-SEM) measurement suggests that RF plasma processes the surface of levitating microorganisms.
