Effect of PDOP polymerization time (i.e., PDOP thickness) on core–shell NPs morphology for 30 min of silver reduction time. TEM images ((a): AuNP@30PDOP@30AgNP, (b): AuNP@60PDOP@30AgNP, and (c): AuNP@180PDOP@30AgNP) of a bimetallic core–shell NP system for different PDOP deposition times (numbers indicate deposition times in min).
