Abstract
New and improved applications of Raman Scattering are disclosed. These applications may be implemented with or without using an enhanced nano-structured surface that is trademarked as the RamanNanoChip™ disclosed in a pending patent. As a RamanNanoChip™ provides much higher sensitivity in SERS compared with conventional enhance surface, broader scopes of applications are now enabled and can be practically implemented as now disclosed in this application. Furthermore, a wide range of applications is achievable as new and improved Raman sensing applications. By applying the analysis of Raman scattering spectrum, applications can be carried out to identify unknown chemical compositions to perform the tasks of homeland security; food, drug and drinking materials safety; early disease diagnosis environmental monitoring; industrial process monitoring, precious metal and gem authentications, etc.
