Molecular Memory

The protein molecules which is called bacteriorhodopsin. It’s purple, absorbs the light and presents in a membrane of a microorganism called halobacterium halobium. Bacteriorhodopsin was chosen because a photocycle, bR-state (0) and Q-state (1) are intermediate states of the molecule and can remain stable during many years.

Essential requirements

  • Bacteriorhodopsin
  • Cuvette
  • Polyacryde gel
  • Battery of lasers
  • Detector array
