Organic-inorganic formamidinium lead triiodide (FAPbI) hybrid perovskite quantum dots (QDs) have garnered considerable attention in the photovoltaic field due to their narrow bandgap, exceptional environmental stability, and prolonged carrier lifetime. Unfortunately, their insulating ligands and surface vacancy defects pose significant obstacles to efficient charge transfer across device interfaces. In this work, an electrostatic harmonization strategy at the interface using a donor-acceptor dipole molecular attachment to achieve enhanced charge separation capabilities on the QD surface is ventured.

Salmonella Typhi can adhere to and build biofilms on the surface of gallstones causing abnormal gallbladder mucosa, which could lead to carcinogenesis. The surface physicochemical properties of microbial cells and materials have been shown to play a crucial role in adhesion. Therefore, the purpose of this study was to investigate, for the first time, the surface properties of nine gallstones and to evaluate the influence of these parameters on the theoretical adhesion of S.

Conjugated polyelectrolytes (CPEs), materials that are defined by a -conjugated backbone and charged ionic functional groups, are frequently prepared through direct polymerization of charged monomer species in aqueous media. This route is, however, often accompanied by labor-intensive work-up procedures, low yields, and ultimately results in materials that are difficult to characterize. To overcome these inconveniences, in this work protection chemistry is applied on sulfonate-functionalized fluorene monomers that are polymerized under standard Suzuki polycondensation conditions to obtain protected donor-acceptor copolymers.

The surge of lateral flow immunoassays (LFAs) stimulates researchers to explore the novel vibrant aggregation-induced emission luminogen (AIEgen)-doped nanoparticles to improve the accuracy and reliability of LFAs. However, the loading amount of AIEgens currently used for the LFA in microspheres is limited due to their symmetrical large conjugated skeleton structure, which significantly reduces the fluorescence brightness of the signal reporter in the LFA. Herein, an ionic AIEgens with a donor-acceptor type was developed as the signal reporter of the LFA for C-reactive protein (CRP).

Article Synopsis
- A new fluorescent molecularly imprinted polymer (DBP-FMIPs) was developed for the specific detection of dibutyl phthalate (DBP) in food samples, using a combination of short amylose, a crosslinking agent, and fluorescent signals.
- *DBP-FMIPs showed high stability and a rapid response time (under 3 minutes), with a linear fluorescence intensity ratio response to DBP concentrations ranging from 0.020 to 20 mg/L, along with a low detection limit of 4.5 μg/L.
- *The probe successfully detected DBP in both liquor and drinking water, proving effective with recoveries of 88-107% and a low relative standard deviation, highlighting its
