Sulfur Species Detection and Fluorescent Probing in Biological Systems
This community develops highly sensitive chemical sensors and fluorescent probes to detect reactive sulfur species, such as hydrogen sulfide, within living cells and tissues. The work focuses on identifying these molecules to understand their roles in cellular signaling, oxidative stress, and disease mechanisms.
The research is dominated by the design of ratiometric fluorescent probes and photoacoustic spectroscopy methods for the selective detection of hydrogen sulfide, sulfur dioxide, and carbon monoxide. A significant portion of the literature addresses the interaction of these sulfur compounds with amino acids and proteins, specifically examining reactive sulfur species and sulfide donors in the context of oxidative stress and signaling pathways. Applications include imaging these species in living cells and rats, as well as the development of gas sensors for environmental or medical monitoring. The work frequently targets the highly sensitive and selective detection of these volatile sulfur species to distinguish them from other reactive molecules in complex biological environments.
The largest share of the community's output is found in sulfur research, accounting for 7.2% of all sulfur research, and 6,704 papers here. This is also the element with the highest paper count within this group.
The community comprises 11,416 papers, with the most frequent venues being Analytical Chemistry, Spectrochimica Acta Part A, and Antioxidants.
Recent work continues to focus on the development of advanced spectroscopic sensors for trace gas detection and the investigation of reactive sulfur species in protein modification and metabolic regulation.
