Article Abstract

A simple naphthalene based fluorescent probe was first time reported as dual sensing of 2,4,6-trinitrotolune (TNT) and 2,4,6-trinitrophenol (TNP) by distinguishable changes in both solution color change and fluorescence within same sample without any mask agent. Upon addition of TNT and TNP, the strong emission quenching at 412nm and a new emission band at 530nm was observed, respectively. In addition, the sensing mechanism was evaluated by DFT calculations by Gaussian 09 software.

Salmonella Typhimurium (S. Typhimurium) is one of the most common food-borne diseases, highlighted as the top food-borne bacterial pathogen in the world with a low infectious dose (1 CFU) and high mortality rate. It is commonly associated with numerous foods such as dairy products, protein sources (multiple types of meat, poultry, and eggs), and bakery products.

The electromobility shift assay (EMSA) is a popular and productive molecular biology tool for studying protein-nucleic acid interactions. EMSA is a technique applied to the revelation of the binding dynamics of proteins, like transcription factors, to DNA or RNA. There are ample essential phases in the technique.

A triphenyl-imidazole end-capped donor-acceptor type potential molecular probe 3 has been designed and synthesized. Probe 3 upon interaction with different classes of metal ions/anions and NPPs displayed high selectivity with CN anion (LOD = 20.42 nM) through fluorescence "turn-Off" response and a naked-eye sensitive visible color change.

Supercoiled (Sc) circular DNA, such as plasmids, are essential in molecular biology and hold strong therapeutic potential. However, they are typically produced in Escherichia coli, resulting in bacterial methylations, unnecessary sequences, and contaminants that hinder certain applications including clinical uses. These limitations could be avoided by synthesizing plasmids entirely in vitro, but synthesizing high-purity Sc circular DNA biochemically remains a significant technical challenge.

Visualizing intracellular glycine with two-dye and single-dye ratiometric RNA-based sensors.

Nucleic Acids Res

September 2025

Department of Chemistry and Henry Eyring Center for Cell and Genome Science, University of Utah, Salt Lake City, UT 84112, United States.

Glycine is an important metabolite and cell signal in diverse organisms, yet tools to visualize intracellular glycine dynamics have not been developed. In this study, diverse and bright RNA-based glycine biosensors were developed by fusing the architecturally complex glycine riboswitch with Broccoli class fluorogenic aptamers. The brightest sensor with the highest activation, glyS, and its two-dye ratiometric counterpart, Pepper-glyS, allowed for visualization of a drug-induced accumulation of endogenous glycine in live Escherichia colicells.
