Fabrication and SERS Performances of Metal/Si and Metal/ZnO Nanosensors: A Review

Surface-enhanced Raman scattering (SERS) sensors are very powerful analytical tools for the highly sensitive detection of chemical and biological molecules. Substantial efforts have been devoted to the design of a great number of hybrid SERS substrates such as silicon or zinc oxide nanosystems coated with gold/silver nanoparticles. By comparison with the SERS sensors based on Au and Ag nanoparticles/nanostructures, higher enhancement factors and excellent reproducibilities are achieved with hybrid SERS nanosensors. This enhancement can be due to the appearance of hotspots located at the interface between the metal (Au/Ag) and the semiconducting substrates. Thus, in this last decade, great advances in the domain of hybrid SERS nanosensors have occurred. In this short review, the recent advances of these hybrid metal-coated semiconducting nanostructures as SERS sensors of chemical and biological molecules are presented.

Target Molecules

AbstractSurface-enhanced Raman scattering (SERS) is a vibrational spectroscopy technique, which is used in the areas of medical diagnostics. This technique use the advantages of biofunctionalized nanoparticles (NPs) for imaging and quantifying of target molecules such as proteins in assays, cells and tissues. The lack of reliability and reproducibility of the results are major challenges in the application of diagnostics based of SERS substrates. The biofunction and success of nanomedical tasks depends on the quality of each involved element like antibodies (IgGs) and nanostructures before, during and after preparation or conjunction with nanoparticles. This short review summarizes current designs of different SERS substrates and highlights the improvement of particularly simple and gentle conjugation methods for targeting research with SERS labels.
