Summary: By conducting laser ablation of core material in a colloidal solution of shell nanoparticles, core-shell nanostructures with enhanced optical absorption and size-dependent thermal diffusivity variations were synthesized. The photocatalytic efficiency of these nanostructures was also found to be enhanced due to electron transfer, showing potential applications in various fields.

Summary: Carbon dots, graphene quantum dots, and other carbon nanocolloids have attracted interest as readily available, non-toxic, and tailorable carbon-based nanomaterials. Their luminescence remains a source of dispute, and the lack of understanding of their optical properties hampers their applications. Researchers are encouraged to explore the complexity of carbon nanocolloids.

Summary: The synthesis of core-shell nanocomposites and the exploration of their nonlinear optical properties, particularly Ag/Au-CdS nanocolloids, show enhanced nonlinear optical behavior with reverse saturable absorption and excellent optical limiting performance. The incorporation of metal nanoparticles in the core-shell nanocolloids leads to an overall enhancement in optical nonlinearities, mainly attributed to strong exciton plasmon interaction and local field enhancement from the metal nanoparticles. These findings suggest potential applications of these nanocomposites in various photonic and optical limiting applications.

Summary: Surface plasmon-coupled emission (SPCE) is a signal enhancement technology that has shown excellent performance in bioimaging. By controlling the excitation angles, the imaging depth can be selectively modulated in a variable-angle nanoplasmonic fluorescence microscopy (VANFM) system based on SPCE. The introduction of Au-Ag alloy nanoshuttles improves imaging performance by mediating the plasmonic properties, leading to better imaging brightness, signal-to-background ratio, and axial resolution.

Summary: This work enhances the photoelectric response of Au@Ag/AgI Schottky contact by modulating localized surface plasmon resonance properties. By manipulating dominant LSPR properties from hot-electron transfer to plasmon-induced resonance energy transfer, additional energy is utilized for carrier generation, leading to a 4 times increase in PE responses.

Summary: In single-particle tracking experiments, monitoring biomolecules usually involves the use of fixed organic dyes or fluorescent fusion proteins, but photobleaching limits observation times. The authors demonstrate long-term single-particle tracking through continuous fluorophore exchange in DNA-PAINT, observing DNA origami on lipid bilayers for tens of minutes, providing insights into cellular processes on relevant timescales.

Summary: By modifying the Cys-CO fabric, a novel composite material with Cys-modified CO fabric decorated with Ag nanoparticles and TA was successfully prepared. Comparative experiments showed that the antibacterial activity of Ag NPs was enhanced after loading TA, while the cytotoxicity of TA was reduced.

Summary: Aquaculture production is negatively impacted by disease outbreaks and the indiscriminate use of antibiotics in controlling infectious diseases has led to the development of antibiotic resistance pathogens. This study investigates the use of myrobalan-mediated green silver nanocolloids (MBNc) as an alternative to antibiotics for controlling the growth of marine pathogens. The MBNc demonstrated excellent antibacterial and anti-biofilm properties, effectively controlling the growth of pathogens and inhibiting the expression of antibiotic resistance genes.

Summary: In this study, a novel fluorescent probe using silver-mediated red emissive carbon dots (RCDs@Ag+) was developed to distinguish cancer cells from normal cells through the bioimaging of glutathione (GSH). The probe showed high selectivity and fluorescence intensity changes upon GSH detection. The method can be used to identify cancer cells overexpressing GSH.

Summary: The use of fluorescence/UV-Vis absorption dual signaling probes is an effective approach to improve the reliability of carbon dots-based sensors. Orange emissive CDs were utilized as dual-functional probes for selectively detecting Ag+ and L-Cysteine with low detection limits. The CDs demonstrate excellent performance in selectively detecting intracellular changes of Ag+ and L-Cys, making them ideal for potential applications in environmental survey and biological assay.

Summary: Hybrid metal-semiconductor nanostructures, particularly Ag-CdS nanorods, have been synthesized and employed as photocatalysts for methyl orange degradation. The catalytic efficiency was found to be length-dependent, with the highest efficiency observed in nanorods of intermediate length. The study also revealed insights into the charge separation-recombination pathway in these nanorods, contributing to a better understanding of their catalytic mechanism.

Summary: This study presents the results of broadband dielectric spectroscopy studies conducted on liquid crystalline octyloxycyanobiphenyl (8OCB) and its colloids with BaTiO3 nanoparticles. The study explores the changes in static and dynamic dielectric properties across different solid and liquid crystalline phases. The results reveal universal scaling patterns for temperature evolution and provide evidence for anomalous values of the fractional Debye-Stokes-Einstein (DSE) exponent. Additionally, the study demonstrates the effect of nanoparticles on the orientation of liquid crystal molecules and presents model explanations for the observed phenomena. New evidence for a premelting effect in the solid phase is also shown.
