Are i‐Motif Structures in DNA Compatible with Cytosine–Ag(I)–Cytosine Base Pairs?

Angewandte Chemie International Edition, EarlyView.
An i‐motif/duplex junction was evaluated with respect to its ability to replace the protons from the hemi‐protonated C:CH+ pairs by AgI ions to form C–AgI–C base pairs. Interestingly, only one such metal‐mediated base pair can be formed before the oligonucleotide rearranges into a duplex structure.

Visualization of Gaseous Ammonia Using an Ionic Liquid‐Based pH‐Responsive Dye

Analysis &Sensing, EarlyView.
An ionic liquid composed of bromocresol purple ([P66614]2[BCP]) is synthesized via an ion‐exchange reaction. The color of [P66,614]2[BCP] changes from yellow to blue after exposure to gaseous NH3. The color change in the [P66614]2[BCP] thin film serves as a visual indicator of pork and salmon decomposition.

Electromembrane Extraction for Multiclass Pesticide Assessment in Soil Matrices: Sustainable Analytical Insights

Analysis &Sensing, EarlyView.
The U‐shaped electromembrane extraction with liquid chromatography‐mass spectrometry enables rapid multiclass pesticide screening in soil. The 15 min, low‐solvent workflow achieves high recoveries and robust linearity, while AGREEprep and GAPI assessments highlight a greener profile compared to literature reports, which represents a smart strategy for ...
