摘要
Over the last few decades, nanomaterials have been playing increasingly important roles in developing analytical biosensors. With a large specific surface area, nanomaterials offer various surfaces for immobilization of biological probes. In addition, taking advantage of their magnetic, catalytic and various optical properties such as fluorescence emission and quenching, light absorption and scattering, Raman enhancement, localized surface plasmon resonance, versatile signaling and signal amplification methods can be realized.
