The stereoelectronic properties of the stabilizing ligands of gold nanoparticles (AuNPs) are shown to play a considerable role in their catalytic efficiency for 4-nitrophenol reduction by NaBH4, consistent with a mechanism involving restructuration of the AuNP surface that behaves as an "electron reservoir".

Toxic-induced cerebellar syndrome (TOICS) poses substantial neurological challenges, given its diverse causes and complex manifestations. Gold nanoparticles (AuNPs) have gained significant attention owing to enhanced biocompatibility for therapeutic interventions. We aimed to investigate the impacts of AuNPs on cerebellar cytomolecular, immunohistochemical and ultrastructural alterations in the context of phenytoin-experimentally induced TOICS.

Currently, no approved antiviral drugs target dengue virus (DENV) infection, leaving treatment reliant on supportive care. DENV vaccine efficacy varies depending on the vaccine type, the circulating serotype, and vaccine coverage. We investigated defective interfering particles (DIPs) and lipid nanoparticles (LNPs) to deliver DI290, an anti-DENV DI RNA.
