Red light can convert a blue membrane into a pink membrane, which has good thermal stability and can be converted back by illumination of blue light. Taking advantage of this property, a reusable biological film based on a deionized blue membrane is demonstrated, which can be used to store and erase images conveniently. The device exhibits a resolution of ∼64 line pairs/mm. The modulation transfer function (MTF) of the blue membrane system is presented.
