Gold nanorods (GNRs) are used in biosensing and imaging applications as they exhibit local surface plasmon resonance (LSPR). The binding of analytes to GNRs alters the local refractive index and produces detectable spectral shifts and this forms the working principle for label-free biosensors. GNR...
