AI Article Synopsis

  • A new fluorescence probe was created to detect biothiols and hypochlorous acid in sequence.
  • The probe uses FRET (Förster Resonance Energy Transfer) and only shows fluorescence when biothiols react first with RSHClO before hypochlorous acid.
  • This ability allows it to imitate biological processes and is ideal for imaging environments where oxidizing and reducing substances can't exist together.

Article Abstract

An 'AND'-based ratiometric fluorescence probe for the sequential detection of biothiols and hypochlorous acid was developed. FRET was observed only when RSHClO reacted with biothiols before reacting with hypochlorous acid, a phenomenon that has been confirmed in aqueous solutions and cells. This feature enables the probe to mimic biological processes and is particularly suitable for imaging oxidizing and reducing substances that cannot coexist.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and influenza A virus are primarily transmitted through droplets or aerosols from patients. The inactivation effects of existing virus control techniques may vary depending on the environmental factors. Therefore, it is important to establish a suitable evaluation system for assessing virus control techniques against airborne viruses for further real-world implementation.

Article Synopsis
  • Hypochlorous acid (HClO) is a reactive oxygen species produced in mitochondria, and its high levels are associated with various diseases, making its detection crucial in medicine.
  • A new dual-modality probe called MB-ClO has been developed, which uses near-infrared fluorescence (NIRF) and photoacoustic (PA) imaging techniques to accurately and sensitively detect HClO in biological systems.
  • MB-ClO shows low toxicity and good water solubility, has a fast response time, and has been successfully tested in a mouse model of rheumatoid arthritis, highlighting its potential for biomedical applications.

The reversal of phototaxis has been observed in a wide range of animal species. However, environmental chemicals that can cause a quick reversal of phototaxis have rarely been reported. Here we identified hypochlorous acid (HClO) as an inducer of phototactic reversal in , also known as sea fireflies.

Hypochlorous acid(HClO)/hypochlorite ion (ClO-) is a highly reactive oxygen species (ROS) that play a crucial role in various biological processes. In this paper, a "turn-on" phosphorescent probe (Ir-TPP) for detecting ClO- in mitochondria was designed and synthesized. In solution, Ir-TPP is minimal emission due to rapid isomerization of C=N-OH as an efficient non-radiative decay process.
