Nonresonant Surface‐Enhanced Hyper Raman Scattering of Aromatic Amino Acids on Gold Nanoparticles

Journal of Raman Spectroscopy, EarlyView.
The surface‐enhanced hyper Raman spectra of the three aromatic amino acids phenylalanine, tryptophan, and tyrosine, obtained with nonresonant excitation at a wavelength of 1064 nm, are reported. The data are discussed in the context of the interaction of the molecules with two gold nanoparticle plasmonic substrates, as well as intermolecular ...

Identification of Natural and Artificial Modifications in DNA at the Nanometer Level

Journal of Raman Spectroscopy, EarlyView.
Short single‐ and double‐stranded DNA sequences with natural and artificial markers are examined at ambient conditions using TERS to identify and localize the labelled nucleobases. The differences between single‐ and double‐stranded DNA should provide clear experimental evidence of the extreme surface sensitivity of TERS.

Filling Uniformity of AgNPs in EMI Shielding Patch Regulated by Surface Morphology

Rare Metals, EarlyView.
ABSTRACT Silver nanoparticles (AgNPs) are extensively employed for electromagnetic interference (EMI) shielding owing to their remarkable conductivity, and are commonly incorporated into polymer matrices. Therefore, the uniformity of the AgNP distribution within the polymer matrix is a crucial factor that affects the EMI shielding performance.
