Engineering exosomal cargo loading via endogenous molecular pathways: Strategies to enhance therapeutic potential

Interdisciplinary Medicine, EarlyView.
This review illustrates how scientists engineer exosomes by hijacking the cell's own cargo‐sorting machinery. These strategies efficiently load therapeutic molecules into natural vesicles, creating powerful next‐generation drug delivery systems (Created with BioGDP.com).

Surface-enhanced Raman scattering of graphene caused by self-induced nanogating by GaN nanowire array

, 2017
A constant height of gallium nitride (GaN) nanowires with graphene deposited on them is shown to have a strong enhancement of Raman scattering, whilst variable height nanowires fail to give such an enhancement.

Development of Selective Plane Illumination Surface Enhanced Raman Scattering Spectral Microscopy for Improved Cellular Imaging

Journal of Raman Spectroscopy, EarlyView.
Selective plane illumination (SPI) is combined with SERS spectral imaging to reduce background, improve image contrast, and enable improved spectroscopy from molecules on the surface of nanoparticles. This approach provides improved imaging and spectroscopy from nanoparticles in complex environments, such as biological cells.

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.
