Summary: In order to improve the prognosis and overall survival of hepatocellular carcinoma (HCC) patients, it is important to identify and resect it at an early stage. However, developing specific fluorescent probes to detect hypochlorous acid (HClO) in liver cells is still challenging. Therefore, the development of a new probe MBH-MT that can detect HClO in biological samples and image it in cells and tissues is of great significance for the diagnosis and treatment of HCC.

Summary: A nanocomposite fluorescent probe was developed for the simultaneous determination of florfenicol and sparfloxacin through fluorescence quenching. The probe consisted of nitrogen-doped graphene quantum dots, cadmium telluride quantum dots, and zinc oxide nanoparticles integrated into a molecularly imprinted polymer. The probe showed high sensitivity and specificity, with good linear relationships and low limits of detection for both analytes. It was successfully applied to determine these antibiotics in food samples with good accuracy, precision, and recovery rates.

Summary: We designed a fluorescent probe, poly(allylamine) hydrochloride (PAH) functionalized copper nanocluster (Cu NC@PAH), for the selective detection of sulfide (S2-) ions in water. The probe showed a significant enhancement in photoluminescence (PL) intensity and quantum yield (QY) after functionalizing with the cationic polymer PAH. The probe also exhibited excellent selectivity and a reasonable quenching response for S2- ions, with a detection limit of 2.39 μM.

Summary: Impurities in trioctylphophine (TOP), specifically the presence of 1-octanol, have been shown to significantly impact the synthesis and photophysical properties of ZnCdSSe/ZnS colloidal nanocrystals. The deliberate addition of 1-octanol into TOP results in smaller particle size and modified spectral shifts, while also increasing nonradiative processes within the nanocrystals. This study suggests that 1-octanol plays a critical role as a functional impurity in tuning the particle size and photophysical processes of the nanocrystals.

Summary: Counterfeiting is a growing problem, and this study proposes an anticounterfeiting technology that utilizes random and inimitable patterns as security tags. The patterns are detectable under UV light and invisible in daylight. By collecting images of the patterns using a smartphone microscope, a database of original patterns is created for authenticity verification. Additionally, a handheld spectrometer is used to obtain the spectral signature of the patterns, enabling a second-step verification. This technology combines ink formula, unclonable security pattern creation, and two-level verification for effective anticounterfeiting.
