Gold nanoparticles (AuNPs) exhibit promising potential as medical materials due to their high biocompatibility, tunable size and shape, excellent drug delivery capabilities, among other unique physicochemical properties. Previous studies have indicated the remarkable anti-inflammatory activity of ginsenoside compound K (CK). However, relatively low bioavailability CK restricts its effective action within biological system. Hence, exploring novel methods based on gold emerges a strategy overcome these challenges in application, thereby enhancing therapeutic effectiveness CK. Probiotic-mediated AuNPs were synthesized using salt lysates Bifidobacterium animalis subsp. lactis. Then, was loaded with form (Bifi-CKAuNPs). The Bifi-CKAuNPs evaluated vitro RAW 264.7 cells vivo mice. NF-κB/ mitogen-activated protein kinases (MAPK) pathway investigated mechanism action.

Selenium nanoparticles (SeNPs) exhibit great potential across a spectrum of applications, yet the development effective methods for their large-scale preparation remains an emerging field. Herein, we propose method to produce SeNPs using nontoxic bulk selenium powder. By dissolving powder in ethylenediamine (EDA) create homogeneous Se–EDA solution, can be easily formed by adding this solution water. The obtained small and uniform size, fine water dispersibility, low cytotoxicity, also exceptional antioxidant activities. Furthermore, conducted comprehensive examination cultivation selenium-enriched bean sprouts. Our findings indicate that exert minimal effect on growth sprouts while substantially boosting levels seleno-amino acids within them. At SeNP concentration 20 mg/L, increase as much 0.182 μg/g. This study not only provides viable approach producing SeNPs, but opens up opportunity selenium-rich foods meet requirements human health.

Abstract Wounds repairing after skin damage or diabetes remain a vast medical challenge, which often faces infection, inflammation, oxidative stress, and scarring. Herein, multifunctional selenium‐albumin nanoaccelerator hydrogel (H‐Se NPs‐Gel) is constructed based on the self‐assembly of human serum albumin (HSA) with selenium nanoparticles (Se NPs) using carbomer as carrier, it has remarkable antibacterial, anti‐inflammatory, antioxidant inhibits scarring properties than Se NPs for wound healing. Compared NPs, H‐Se exhibit smaller particle sizes, exceptional stability, better antibacterial activity against common bacteria MRSA, superior anti‐inflammatory capabilities in vitro without toxicity cells. Importantly, exhibits efficacy to NPs‐Gel accelerating healing full‐thickness defects diabetic wounds mice. Interestingly, hypertrophic scar (HTS) model, more effective inhibiting collagen formation suppress scarring, mediated by inhibition CD36. The antagonistic effect CD36 also proved overexpression model. Furthermore, demonstrates excellent safety mice systemic toxicity. an safe therapy strategy promoting reducing clinic.
