Surface-enhanced Raman scattering (SERS), as a powerful spectroscopic analysis tool, has the capability to provide information on material fine structures and chemical compositions [1], [2]. Although the Raman signal of molecules is usually weak, the following two enhancement mechanisms are well-known to achieve an order of magnitude improvement in the Raman signal. The dominant mechanism is electromagnetic enhancement mechanism (EM) specific to noble metal substrates [3].

Enhancing Substance Identification in Raman Spectroscopy Using Deep Neural Convolutional Networks with Attention Mechanism Raman spectroscopy is widely used for substance identification, providing molecular information from various components alongside noise and instrument interference. Consequently, identifying components based on Raman spectra remains challenging.

AbstractPreclinical and clinical translational research supports the role of an ω-3 fatty acid diet for prostate cancer prevention and treatment. The anti-prostate cancer effects of an ω-3 diet require a functional host g-protein coupled receptor 120 (GPR120) but the underlying effects on the tumor microenvironment and host immune system are yet to be elucidated.
