Physical and Methodological Perspectives on the Optical Properties of Biological Samples: A Review

Photonics, 2021
The optical properties of biological systems can be measured by imaging and microscopy methodologies. The use of X-rays, γ-radiation and electron microscopy provides information about the contents and functions of the systems. The need to develop imaging

Optical Properties of Gold Nanorings [PDF]

Physical Review Letters, 2003
The optical response of ring-shaped gold nanoparticles prepared by colloidal lithography is investigated. Compared to solid gold particles of similar size, nanorings exhibit a redshifted localized surface plasmon that can be tuned over an extended wavelength range by varying the ratio of the ring thickness to its radius.
