Photochemical damage from ZnS was also unlikely. Nucleobases absorb light
at 260–270 nm and emit it at 300–310 nm [159,302]. ZnS nanoparticles absorb
light in a broad range up to approx. 350 nm and emit light at 420–470 nm
[144,303]. Therefore the radiation energy could be transferred from the adsorbed
nucleotides to a ZnS template (and thus contribute to the CO2 reduction), but
not in the reverse direction. Hence, the quanta directly absorbed by the ZnS templates
would not damage the adsorbed RNA-like replicators.
