Direct Base-to-Base Transitions in ssDNA Revealed by Tip-Enhanced Raman Scattering [PDF]

arXiv, 2016
In the present contribution, specifically designed single-stranded DNA (ssDNA) sequences composed of adenine and cytosine were used as nanometric rulers to target the maximum achievable spatial resolution of tip-enhanced Raman spectroscopy (TERS) under ambient conditions.

Continuous Light‐Induced Water Oxidation In Polyoxometalate‐Based Photocatalytic Protocells And Prototissues

Chemistry – A European Journal, Accepted Article.
The bottom‐up construction of leaf‐like materials capable of using visible light and water to produce oxygen and chemical energy is a major goal of artificial photosynthesis. In this work, we show that robust artificial cells (protocells) prepared by the membranization of polymer/nucleotide coacervate droplets with a bio‐inspired Ru‐based ...

Flavin nucleotides in human lens: Regional distribution in Brunescent cataracts

Indian Journal of Ophthalmology, 1998
The biochemical mechanism(s) underlying brunescent cataracts remain unclear. Oxidative stress due to reactive oxygen species may have a role in the pigmentation process in eye lens.

Advances in Isotope Labeling for Solution Nucleic Acid Nuclear Magnetic Resonance Spectroscopy

ChemPlusChem, EarlyView.
Recent advances in the field of nucleic acid nuclear magnetic resonance (NMR) are presented. Stable isotope labeling protocols and new approaches to segmentally label nucleic acid with NMR‐active residues are summarized. The novel methods will have a strong impact on the future of nucleic acid NMR and the characterization of structure and dynamics of ...
