Optical biosensors with localized surface-plasmon resonance (LSPR) are discussed. LSPR nanosensors can be implemented using simple and low-cost equipment for unpolarized and UV-visible extinction spectroscopy in transmission or reflection geometry. The use of nanosphere lithography (NSL) for the fabrication of LSPR nanosensor is discussed. The sensitivity, reversibility, reusability, selectivity and biocompatibility of LSPR nanobiosensors with respect to antigen/antibody reactions is also discussed.
