Mechanical Caging of Nucleic Acids Enabled by Light‐Activated Synthetic Molecular Motors

Angewandte Chemie, EarlyView.
A synthetic light‐driven molecular motor imposes mechanical constraints on nucleic acids, enabling “mechanical caging” as a new mode to regulate DNA structure and function through mechanical input rather than chemical masking. ABSTRACT Control over nucleic acid activity is central to biotechnology and therapeutic development.

Glyoxal fixation facilitates transcriptome analysis after antigen staining and cell sorting by flow cytometry.

PLoS ONE, 2021
A simple method for extraction of high quality RNA from cells that have been fixed, stained and sorted by flow cytometry would allow routine transcriptome analysis of highly purified cell populations and single cells.

Induction and Stabilization of Peptide Alpha‐Helices on Silica Nanoparticles

Angewandte Chemie, EarlyView.
Covalent docking turns silica nanoparticles (SNPs) into α‐helix‐stabilizing surfaces. Dynamic imine formation allows peptides with lysine residues aligned on one helical face to adapt to the surface before reduction locks the structure in place, while preserving the opposite face for functional recognition.

Yields of oxidized volatile organic compounds during the OH radical initiated oxidation of isoprene, methyl vinyl ketone, and methacrolein under high-NO_x conditions [PDF]

Atmospheric Chemistry and Physics, 2011
We present first-generation and total production yields of glyoxal, methylglyoxal, glycolaldehyde, and hydroxyacetone from the oxidation of isoprene, methyl vinyl ketone (MVK), and methacrolein (MACR) with OH under high NOx conditions.

The Reaction of 1,6-Diamino-4-aryl-2-oxo-1,2-dihydropyridine- 3,5-Dicarbonitriles with Certain Electrophilic Agents

Chemistry Proceedings, 2023
The reaction of 1,6-diamino-2-oxo-1,2-dihydropyridine-3,5-dicarbonitriles, which are easily available through the reaction of cyanoacetohydrazide with arylmethylene malononitriles, with ninhydrin leads to the formation of novel dihydroindeno[1,2-e]pyrido[

Oligomer Formation in Evaporating Aqueous Glyoxal and Methyl Glyoxal Solutions

, 2016
Glyoxal and methyl glyoxal are common secondary atmospheric pollutants, formed from aromatic and terpene precursors. Both compounds are extremely water-soluble due to dihydrate formation and partition into cloudwater.

Assessment of Melatonin-Cultured Collagen/Chitosan Scaffolds Cross-Linked by a Glyoxal Solution as Biomaterials for Wound Healing

Antioxidants, 2022
Chitosan (CTS) and collagen (Coll) are natural biomaterials that have been extensively used in tissue engineering or wound healing applications, either separately or as composite materials.
