Herein, we describe the results of fluorescence
microscopy imaging of peridinin-chlorophyll-protein
(PCP) photosynthetic complex mixed with reduced
graphene oxide (rGO). Upon incorporation of rGO the
fluorescence image of PCP changes substantially from
one characterized by uniform intensity towards a more
complex pattern. The isolated bright spots feature up
to ten times higher emission intensity compared to the
fluorescence of PCP in the reference sample, where no
rGO was added. The number of the bright spots increases
with increasing rGO concentration. At the same time the
fluorescence intensity away from the bright spots in the
PCP/rGO hybrid system is quenched in comparison to the
PCP – only reference.
