Biofunctionalization of gold nanoshells monitored by surphase plasmon resonance

In this paper we focus on the preparation and the biofunctionalization of GNSs. The coverage of the GNSs on the surfaces of the silica NPs was evaluated using UV-VIS/NIR spectroscopy. The surphase plasmon resonance (SPR) wavelengths of these GNSs were tunable from visible to near infrared.
