Summary: A protocol for colorimetric detection of potentially hazardous Hg2+ ions was developed using sonochemical-assisted eco-friendly synthesized silver nanoparticles (AgNPs) prepared with avocado seed extract. The AgNPs showed good selective sensing response towards Hg2+ ions with a color change and disappearance of the surface plasmon resonance (SPR) band. The unmodified green synthesized AV-AgNPs exhibited promising potential for on-site detection of Hg2+ in water samples.

Summary: In recent years, there has been significant interest in resonance energy transfer involving noble metallic nanoparticles. This review summarizes the advancements in resonance energy transfer, which has been widely used in biological structures and dynamics. The presence of surface plasmons near noble metallic nanoparticles leads to strong surface plasmon resonance absorption and local electric field enhancement, making the resulting energy transfer useful in various applications such as microlasers, quantum information storage devices, and micro-/nanoprocessing. This review discusses the basic principles of noble metallic nanoparticles and highlights progress in resonance energy transfer, including fluorescence resonance energy transfer, nanometal surface energy transfer, plasmon-induced resonance energy transfer, metal-enhanced fluorescence, surface-enhanced Raman scattering, and cascade energy transfer. The review concludes with an outlook on the development and applications of this transfer process, offering theoretical guidance for distance distribution analysis and microscopic detection.

Summary: Using electron spin resonance spectroscopy, it has been demonstrated that morphological asymmetries in small spheroidal metallic nanoparticles significantly affect the electronic behavior of states near the metal's Fermi energy. The study found that morphological effects were more important than size distributions in explaining the asymmetry in electronic behavior, and this was consistent across various particles made from different metals. Additionally, the study also showed that morphological changes can tune the electronic properties of even small particles, as evidenced by the modeling used to explain asymmetries in both electron spin resonance spectra and plasmon spectra.

Summary: Lichens are symbiotic organisms composed of fungi and photosynthetic algae，and lecanoric acid is an important secondary metabolite with antibiotic properties. This study aimed to produce lecanoric acid from Parmotrema austrosinense lichen and evaluate its efficacy against tea fungal pathogens. The results demonstrated that lecanoric acid exhibited significant antifungal activity, surpassing companion systemic and botanical fungicides in terms of growth inhibition. The inhibition rate varied among tea pathogens, with tea leaf disease-causing pathogens showing the highest percentage of growth inhibition. These findings suggest that lecanoric acid has an inhibitory effect on tea pathogens due to its antibiotic properties and fungicidal action.
