Espectroscopia Raman com aumento de campo local: categorização da técnica no campo da instrumentação

Abstract

The present work categorizes the technique of Tip-Enhanced Raman Spectroscopy within the field of instrumentation, as a first step towards the future development of feasibility analyses for the generation of domestic commercial product in the instrumentation for microscopy and optical spectroscopy to study materials at the nanoscale. We first present a discussion of the categorization of instrumentation in general, focusing on the classifications presented in the literature. It follows the state of the art, including a discussion of its stage in terms of scientific evolution and correlated patents. Based on this, the technique is identified as hybrid instrumentation with respect to function, branching in terms of trajectory, and autonomous regarding the work environment, according to the classification proposed by Marcovich and Shinn (2017). This preliminary study points, however, to the need to develop a categorization applied to scientific instrumentation in the field of nanotechnologies.
