Description
Summary:Often touted as a label-free sensing technique, surface plasmon resonance based sensing and imaging have become commercially available for quite some time, and are employed in applications such as studying protein-protein interactions, immunochemical procedures and drug-receptor binding. Nanoporous gold nanoparticles and arrays Nanoporous gold (NPG) nanoparticles and arrays can be formed by a hybrid fabrication process combining top-down lithography and bottom-up atomic dealloying (14,15). A number of label-free biosensing applications have been developed in the past 4years for nucleic acids, proteins, enzymes, metabolites, neurotransmitters, polycyclic aromatic hydrocarbons, carcinogenic environmental and food contaminants, and etc (11,19-23). Microfluidic surface-enhanced Raman scattering sensor with monolithically integrated nanoporous gold disk arrays for rapid and label-free biomolecular detection.
