Published: November 2022

A split intein-based method has been developed to detect peptide:-glycanase (PNGase) activity in live cells. PNGase cleaves the linkage between '-diacetylchitobiose and the Asn side-chain of N-intein peptides and the products react rapidly with C-intein by protein trans-splicing to generate an active luciferase.

Over recent years, the LUMinescent AntiBody Sensor (LUMABS) system, utilizing bioluminescence resonance energy transfer (BRET), has emerged as a highly effective method for antibody detection. This system incorporates NanoLuc (Nluc) as the donor and fluorescent protein (FP) as the acceptor. However, the limited Stokes shift of FP poses a challenge, as it leads to significant spectral cross-talk between the excitation and emission spectra.

Lead (Pb) is a highly toxic heavy metal that causes significant health hazards and environmental damage. Thus, the detection and removal of Pb ions in freshwater sources are imperative for safeguarding public health and the environment. Moreover, the transformation of single resources into multiple high-value products is vital for achieving sustainable development goals (SDGs).

Afterglow luminescence provides ultrasensitive optical detection by minimizing tissue autofluorescence and increasing the signal-to-noise ratio. However, due to the lack of suitable unimolecular afterglow scaffolds, current afterglow agents are nanocomposites containing multiple components with limited afterglow performance and have rarely been applied for cancer theranostics. Herein, we report the synthesis of a series of oxathiine-containing donor-acceptor block semiconducting polymers (PDCDs) and the observation of their high photoreactivity and strong near-infrared (NIR) afterglow luminescence.

Hypochlorous acid (HClO) is released by immune cells in the immune system, and it helps the body fight off infections and inflammation by killing bacteria, viruses, and other pathogens. However, tissue damage or apoptosis may also be induced by excess HClO. On this basis, we designed the probe TPE-NS by choosing tetraphenylethylene (TPE) as the luminescent unit and dimethylthiocarbamoyl chloride as the recognition site.

Herein, highly fluorescent sulfur and nitrogen co-doped carbon dots (N, S-CDs) had been employed as a fluorescent probe to analyze Cu in drinking water. The biogenic creatinine is known to form a stable complex with Cu; hence, it was rationally selected as a bioinspired nitrogen substrate for the first time to enhance N, S-CDs selectivity towards Cu. Moreover, the literature was surveyed to guide the selection of sulfur and carbon sources to optimize N, S-CDs quantum yield (QY), so thiourea and disodium edetate are co-carbonized with biogenic creatinine at 270°C for 40 min and characterized using different techniques.
