Since 1970s surface-enhanced Raman spectroscopy (SERS) had gone through a tortuous pathway for developing to a versatile analytical technique. The materials-, morphologic- and molecular-generalities were questioned often, such as by analytical and surface science communities. Based on the fact that SERS is mainly nanostructure- and SPR-enhancement phenomenon, Together with other groups we have aimed to break the development bottlenecks and expand the practical application since 1980s. We combined experimental and theoretical approaches to show that SERS can be directly generated on pure Pt and Fe group metals, which were commonly considered as non-SERS active metals. We home-made a Raman-STM combined system by which STM images of electrode surfaces and SERS spectra could be simultaneously, four years earlier than that of invention of tip-enhanced Raman spectroscopy (TERS). We invented shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS), capable of probing various metal, semiconductor, living cell or fruit surfaces. Molecular-level investigations on diverse adsorbates at atomically flat surfaces have been realized. Facing the growing food safety and drug abused problems, we focused on the on-site quick SERS detection technique with portable Raman instruments. The protocols for almost 100 targets in various food and drug samples have developed, and part of them has entered the market.<br/>
