- •
The surface plasmon resonance (SPR) absorption of hollow gold nanospheres (HGNs) can be tuned by controlling the diameter and shell thickness to cover the entire visible to near IR (NIR) region of the spectrum.
- •
HGNs show enhanced performance photothermal therapies (PTTs) of cancer due to their ability to generate strong and narrow SPR, small size, and ease of bioconjugation.
- •
HGNs strongly enhance imaging applications due to their resistance to photobleaching and strong absorption as well as scattering of light in the desired wavelength regions.
