genetics concerning the study of the genomes of organisms; an organism’s
complete set of DNA is called its genome), proteomics (the study of an organ-

Find the SPR frequency of gold NPs, and the corresponding wavelength
in vacuum taking the electron effective mass (m
e
) as 10%–15% higher
than the free electron mass value. Discuss the effect of the dielectric
medium on the obtaine ...
