Gold nanoparticles (AuNPs) have unique features that might lead to the development of a new class of diabetic medicines. AuNPs were biosynthesized utilizing sodium-alginate. UV-Vis-spectroscopy, Fourier transforms infrared, field emission scanning electron microscopy (FESEM), and energy dispersive X-ray were used to examine the particles. The potential of AuNPs for improving the diabetes condition was examined along with swimming in rats. FESEM image revealed the spherical morphology with an average particle size of 106.6 ± 20.8 nm. In the diabetic group, serum glucose, blood urea nitrogen (BUN), creatinine, cholesterol, and triglyceride (TG) levels were significantly higher than the control group. Low-density lipoprotein (LDL) was significantly higher and high-density lipoprotein (HDL) was significantly lower in the diabetic group compared to the control group. Malondialdehyde (MDA) levels were also significantly higher in the D group. However, in the groups treated with swimming and gold, these parameters were significantly improved. Specifically, serum-glucose, BUN, creatinine, cholesterol, and TG levels were significantly reduced, while LDL was significantly decreased in the diabetic + swimming + AuNPs group and HDL was significantly increased in the diabetic + AuNPs group. MDA levels were significantly decreased in the treated groups, and other antioxidants were significantly improved in the diabetic + swimming + AuNPs group. Catalase levels were also significantly improved in the D + gold group. It can be concluded that both AuNPs and swimming can decrease diabetic complications.

Controlling the size of gold nanoparticles (AuNPs) has been critical in diagnostics, biomolecular sensing, targeted therapy, wastewater treatment, catalysis, and sensing applications. Ultrasmall AuNPs (uAuNPs), with sizes Ranging from 2 to 5 nm, and gold nanoclusters (AuNCs), with sizes less than 2 nm, are often dealt with interchangeably in the literature, making it challenging to review them separately. Although they are grouped in our discussion, their chemical and physical properties differ significantly, partly due to their electronic properties.

Amino acids are natural organic biomolecules with higher biocompatibility and are crucial for life reactions. Biomolecule-dependent functionality of metallic nanoparticles can tailor them with more effectiveness and biocompatibility. This study was designed to assess the histopathological aspect of gold nanoconjugates (AuNCs) exposure for antioxidant potential in albino mice (Mus Musculus).

Poor vascularization and infections hinder diabetic wound healing, posing challenges in therapy development. A multi-action approach incorporating Dicer-substrate small interfering RNA (DsiRNA) against the prostaglandin transporter (PGT) gene and gold nanoparticles (AuNPs) into a Pluronic F-127 (PF127) gel was developed. This study aimed to upscale AuNP biosynthesis using Lignosus rhinocerotis (tiger milk mushroom, TMM) extract and chitosan as stabilizers.

Background: Due to the unique characteristics of gold nanoparticles, including low toxicity, tissue compatibility, high surface-to-volume ratio, excellent stability, lack of immunogenicity, and the ability to cross the blood-brain barrier, gold nanoparticles can affect brain cells and impact neuronal functions. This study aimed to investigate the effect of gold nanoparticles (AuNPs) on rats' anxiety, memory, and learning ability.
Method: This study was conducted on 35 male Wistar rats that were obtained from the Animal Center of Baqiyatallah University.

An innovative fluorometric method has been developed to detect nitric oxide radicals (•NO) and NO-scavenging activity of antioxidants. Nitric oxide radicals were generated from the precursor sodium nitroprusside (SNP), and gold nanoparticles modified with a thiolate ligand (4-hydroxythiophenol) (AuNPs@4-HTP) was designed as the detector probe; addition of •NO to the thiophenol ring of AuNPs@4-HTP was followed by autoxidation of the NO-substituent to -NO which in turn interacted with the fluorophore N-(1-naphthyl)ethylenediamine (NEDa) as a Lewis acceptor-donor pair. As a result of the interaction of nitrated AuNPs@4-HTP with the amine groups of NEDa, the fluorescence of NEDa was quenched.
