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.

Molecular Cages as Probes in Indicator Displacement Assays: The Case of Scopolamine Detection

Angewandte Chemie International Edition, EarlyView.
In this research, we show the concept of molecular cages as probes in indicator displacement assays, focusing on scopolamine detection, a drug often used in drug‐facilitated sexual assaults. Drug sensing occurs via the drug‐induced transformation of non‐emissive [Fluorescein2⊂Cage] complex into [Scopolamine⊂Catenane] and highly emissive free ...

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.
