The present project aims to develop substrates using spectroscopy enhanced Raman (SERS) that are versatile in presentation-paper, 3D printing, silicon solid supports, metallic Al, Au, Ag, AuAg, in colloidal presentation, etc., and optimized by type of NPs used and towards the molecules to which they are focused, i.e., problems to attack in the areas of health, safety or agri-food, which help to simplify the detection of problem molecules, their precursors and their derivatives, in addition to their own pesticides in the use of regional crops, problems to be attacked in the areas of health, safety or agri-food, which help to simplify the detection of problem molecules, their precursors and their derivatives, as well as pesticides in the use of regional crops, such as chili, lettuce, oranges, corn, etc., which farmers are known to be interested in monitoring due to the economic repercussions they suffer when exceeding the minimum permitted levels, to mention two fields of high interest at regional and national level due to their social and economic repercussions.
The design and construction of these substrates developed at IPICYT results in the routine use of this technique by non-specialists (farmers, doctors, inspectors, quality control), using reliable and cost-effective nanostructured substrates, at prices competitive with those available in the market, with portable Raman equipment (point of care) and a library of SERS signals optimized for various specific areas such as Health and Biomedical, Agri-Food, Human Safety, Quality Control in various industries, Water Quality Control, etc.
The most important element of the SERS technique is the substrate and, consequently, the history of SERS has been largely that of the development of signal-enhancing materials, and over the last two decades, with the particular use of substrates with plasmonic nanostructured systems that provide an intense increase in electromagnetic response.
In qualitative terms, the execution of the proposal which basically involves the formulation of versatile substrates for measurements of problem analytes, could benefit diverse populations such as:
In quantitative terms, it is difficult to precisely estimate the specific population that would benefit from a development such as the one proposed in this project, since it depends on the adoption and application of SERS substrates in different fields. However, the potential for impact is broad, as Raman spectroscopy and analyte detection have applications in various areas of research, development and quality control in different industrial sectors. Therefore, the number of people and organizations benefiting could be significant depending on the adoption and utilization of these substrates in the future.
