A schematic representation of a multimode microscopy setup integrated with VegaPhoton SI adaptor facilitating the visualization of red, green, blue, and yellow color scattering plasmonic NPs on H&E-stained cytology samples. As illustrated, different plasmonic NPs with their unique resonance peak on single cell are clearly visible in this setup. The multimode microscopy setup is composed of a (I) transmission microscopy (white light source) and (II) 3D dark-field microscopy (SI observation of plasmonic NPs) and can independently visualize each mode by simply switching from one mode to another.
