Optical Properties of Silver Nanowires Conjugated with Protein [PDF]

open access: yesCommunications in Physics, 2021
Optical properties of protein-conjugated metallic nanowires are theoretically investigated based on the Mie theory and the core-shell model. Our numerical calculations show that optical spectra of protein-conjugated nanowires can have more a maximum compared to these nanowires without biomolecules.
