We show that imaging contrast can be greatly enhanced as yeast cells are placed on a silver nano-particle array. Its near- and far-field traits, revealed by electrodynamic simulations, illustrate that the enhancement is attributed to the sensitivity of its plasmonic characteristics to the attached cells. This study demonstrates that the silver nanoparticle array can serve as the agent for concurrently enhancing Raman scattering and imaging contrast of microorganisms for identification and examination. © 2014 Optical Society of America. |
