Summary: In this study, Sn and Ag doped PbS/PVA nanocomposites were successfully prepared using the chemical bath deposition method. The doping process altered the shape of the grains and reduced the optical sensitivity. Optical absorption spectra showed an increase in band gaps, indicating enhanced optical resistivity. These findings have practical implications in the design of linear and nonlinear optical devices, such as sensors, optical switches, and limiters.

Summary: An effective strategy is proposed to construct a highly sensitive ratiometric fluorescence sensing platform for microcystins (MCs) based on a dummy molecularly imprinted polymer using metformin as a template. The imprinted nanohybrids of carbon dots (CDs) combined with fluorescein isothiocyanate (FITC) are synthesized (CDs-FITC-SiO2@MIP), in which the CDs and FITC serve as assisted response signals and reference enhancement signals, respectively. This method has great potential for monitoring MCs in complex systems.

Summary: An ultrasensitive electrochemiluminescence (ECL) immunosensor with magnetic separation was constructed for the detection of SARS-CoV-2 nucleocapsid protein (NP) using dendritic mesoporous silica nanospheres loaded with CdSe/ZnS quantum dots (DMSN@QDs) as signal labels. The DMSN@QDs exhibited good ECL efficiency and were able to increase the loading capacity of QDs and prevent their aggregation. The ECL immunosensor showed a linear relationship for NP concentrations ranging from 0.005 ng mL(-1) to 50 ng mL(-1), with a limit of detection of 3.33 pg mL(-1). It was successfully applied to detect NP in human serum samples with satisfactory recovery, providing a new method for NP detection and expanding the application field of DMSN.

Summary: Investigations of the behavior and effects of engineered nanoparticles (ENPs) on human health and the environment require understanding their fate and transport in environmental compartments. One strategy is to use mimics of ENPs with unique detectable properties, such as quantum dots (QDs). QDs, composed of different metals or carbon, can be tracked and quantified using fluorescence microscopy, photometric techniques, and electron microscopy.
