Characterization and Potential Application of Next Generation Commercial Surface Enhanced Raman Scattering Substrates

摘要: Abstract : The development of a sensing platform capable detecting and identifying hazards, including biological, chemical, energetic platforms, is long sought-after goal the Army first responder communities. Surface-enhanced Raman scatting (SERS) spectroscopic technique gaining popularity as solution to many needs due its numerous advantages such high sensitivity, little no sample preparation required, use in environmental settings. Despite all SERS, it still remains marginalized primarily challenges fabricating reliable, highly sensitive reproducible nanoscale surface. In this work, we show that these have been overcome with newly developed commercially available Klarite SERS substrate. These substrates are fabricated fashion similar standard substrates, but changes size spacing inverted pyramidal structure there an overall increase capabilities up 4 orders magnitude. technical report, next-generation (308 309) characterized, analyte sensitivity at both 633 nm 785 demonstrated, preliminary non-optimized efforts biological presented.
