You bought bacteria,grew it, synthesized it , now its time to make a film with your rhodopsin.
Bacteriorhodopsin oriented in polyvinyl alcohol films as an erasable optical storage medium
Zhongping Chen, Aaron Lewis, Hiroyuki Takei, and Isaiah Nebenzahl
Films of oriented bacteriorhodopsin have been formed in polyvinyl alcohol with excellent optical quality.
Images with high contrast have been impressed and erased on these films. Second-harmonic microscopy has
been used to read the image on a bacteriorhodopsin-polyvinyl alcohol film without erasure. The potential of
these films for molecular information storage and computation is discussed.
