Surface-Enhanced Raman Spectroscopy (SERS) for characterization SARS-CoV-2 [PDF]
Journal of Saudi Chemical Society, 2022 Abstract Background: The current coronavirus disease 2019 (COVID-19) pandemic caused by SARSCoV-2 standard assay relies on RNA purification, one-step retrotranscription, and quantitative PCR to identify SARS-CoV-2 (RT-qPCR). However, this standard procedure usually takes 4.0 h, particularly for the RNA extraction step.

Study of Chemical Enhancement Mechanism in Non-plasmonic Surface Enhanced Raman Spectroscopy (SERS). [PDF]
Front Chem, 2019 Surface enhanced Raman spectroscopy (SERS) has been intensively investigated during the past decades for its enormous electromagnetic field enhancement near the nanoscale metallic surfaces. Chemical enhancement of SERS, however, remains rather elusive despite intensive research efforts, mainly due to the relatively complex enhancing factors and ...

Remote plasmonic-enhanced Raman spectroscopy with the plasmon-molecule coupling in distance over 100 nm [PDF]
EPJ Web of Conferences, 2023 We propose remote plasmonic-enhanced Raman scattering (RPERS) spectroscopy for molecular sensing and imaging applications. RPERS requires no contact between analyte molecules and metallic nanostructures, which overcomes the limitations of surface ...

Bioaerosol characterization by surface-enhanced Raman spectroscopy (SERS) [PDF]
Journal of Aerosol Science, 2005 It is demonstrated that bioaerosols can be characterized by their surface-enhanced Raman spectra. Preliminary studies showed that Raman spectra of aqueous suspensions of Escherichia coli, Pseudomonas aeruginosa, and Salmonella typhimurium can be obtained by mixing them with a nanocolloidal suspension of silver.

Novel Liposome-Based Surface-Enhanced Raman Spectroscopy (SERS) Substrate [PDF]
The Journal of Physical Chemistry Letters, 2017 Although great strides have been made in recent years toward making highly enhancing surface-enhanced Raman spectroscopy (SERS) substrates, the biological compatibility of such substrates remains a crucial problem. To address this issue, liposome-based SERS substrates have been constructed in which the biological probe molecule is encapsulated inside ...
