Summary: The study presents a mild and fast method for synthesizing carbon nanoclusters (CNCs) with strong green fluorescence. The CNCs can sensitively detect the presence of ascorbic acid (AA) and have been successfully applied to detect AA in real samples. The as-prepared CNCs also exhibit excellent fluorescence property and low toxicity, making them suitable for fluorescent printing.

Summary: Monitoring neurotransmitter concentrations in the brain is crucial for studying and diagnosing neurological diseases, but sensitivity has been a challenge. In this study, a new electrochemical sensor using graphene oxide and platinum micro particles was developed for simultaneous determination of epinephrine, ascorbic acid, and uric acid. The sensor exhibited excellent catalytic activity and wide linear response ranges for all three species. It can also determine epinephrine in the presence of other substances and is feasible for application in biological fluids.

Summary: Metal nanoclusters (NCs) with excellent photoluminescence properties have been successfully regulated using a supramolecular self-assembly strategy, resulting in a phosphorescent hydrogel with stable and bright luminescence attributed to aggregation-induced emission (AIE) phenomenon. This research enriches the self-assembly system for enhancing the AIE of metal NCs and demonstrates the potential of the prepared hybrid films as good candidates for optical materials.

Summary: The derivatisation of tetraphenylethylene is widely used to synthesize molecular sensor for detecting explosives and other analytes, but its effects have been poorly studied. In this study, we report the detection of various nitro phenols using fluorescence signals produced by TPPE. The fluorescence of TPPE at 411 nm and 432 nm is quenched in the presence of TNP through electron transfer mechanism. Furthermore, TPPE shows strong binding affinity and selectivity towards TNP over other nitroaromatic analytes, with a sensing detection limit of 4.58 x 10-9 M. Detailed molecular simulation experiments support the sensing mechanism and provide insight into the interaction between TPPE and TNP.

Summary: In this study, an ingenious method for detecting trace amounts of ascorbic acid (AA) was presented using a fluorescent sensing system. The system was composed of periodate (IO4 ) and nitrogen-boron co-doped carbon dots (N, B-CDs). Highly photoluminescent carbon dots were synthesized using a one-step hydrothermal method, and the fluorescence of N, B-CDs was statically quenched by IO4 . By pre-adding ascorbic acid, the fluorescence quenching process was inhibited, allowing for the detection of AA with an extremely low limit of detection.
