Enhancing bright-field image of microorganisms by local plasmon of Ag nanoparticle array

Inspecting biological cells with bright-field light microscopy often engenders a challenge, owing to their optical transparency. We show that imaging contrast can be greatly enhanced as yeast cells are placed on a silver nanoparticle array. Its near- and far-field traits, revealed by electrodynamic...
