  Proteinoids, or thermal proteins, are produced by heating amino acids to
their melting point and initiation of polymerisation to produce polymeric
chains. In aqueous solutions proteinoids swell into hollow microspheres. These
microspheres produce endogenous burst of electrical potential spikes and change
patterns of their electrical activity in response to illumination. We report
results of detailed investigation on the effects of white cold light on the
spiking of proteinoids. We study how different types and intensities of light
determine proteinoids' spiking amplitude, period, and pattern. The results of
this study will be utilised to evaluate proteinoids for their potential as
optical sensors and their application in unconventional computing.
