Gold nanoparticles (AuNPs) were synthesized with water-soluble chitosan serving as the reducing agent and stabilizer. Subsequently, they characterized by UV–vis, TEM, FT-IR, XRD. The impact of concentration molecular weight on morphology AuNPs was investigated. in vitro antioxidant activity against OH·, ABTS·+, DPPH, NO· assessed. Additionally, catalytic reduction toward 4-nitrophenol (4-NP) presence NaBH4 evaluated. results indicated that various morphologies, including spherical, anisotropic AuNPs, triangular Au nanoplates different particle sizes, could be controlling chitosan. It discovered correlated their morphology. Spherical a particles diameter 15 nm exhibited highest activity, estimated IC50 values 24.6 ± 1.9, 15.6 3.2, 22.6 15.1 1.9 μg/mL for NO·, respectively. Triangular showed reaction rate constant of0.3889 min−1 turnover frequency 7.52 × 10−5mol/(mg·min), well lowest activation energy 24.1 kJ/mol.

Rhodamine B is a carcinogenic additive that can trigger free radicals. Bajakah wood ( Spatholobus littoralis ), red betel Piper crocatum and Papua fruit Pandanus conoideus ) are herbs with high antioxidants to ward off This study analyzed the ability of three fight radicals due rhodamine injection. Eighty-five mice Mus musculus were divided into 17 treatment groups. The groups consisted without B, only combination certain herbal doses. Free radical measurements carried out using Electron Spin Resonance (ESR), cell damage was observed through histopathology. effective doses 7.27 mg/ml (Bajakah), 3.95 (red betel), 8.83 (Papua fruit). decreased 0.6 A.u 0.8 0.7 Histopathology showed decrease in by 44.7% 30.2% 26.6% results correlate damage. most herb for preventing

Abstract Developing micro‐/nanomotors that convert a chemical energy input into local gradient field and motion is an appealing but challenging task holds particular promise for the intersection of materials nanoengineering. Over past two decades, remarkable advancements have refined these out‐of‐equilibrium chemically powered micro‐/nanomotors, enabling them to orchestrate in situ transformations dynamically change environments. The ionic products, radicals, gases, electric fields from active reshape microenvironment, paving way ecofriendly disease interventions. This review discusses state‐of‐the‐art reactions propel energy‐consuming elucidates emerging implications their products on biological systems. Particular emphasis has been placed potential neural modulation, reactive oxygen species (ROS) regulation, synergistic tumor therapy, antibacterial strategies, tissue regeneration. Collectively, sketches provide landscape therapeutic modalities, heralding new era biomedicine. By harnessing product this matter, we envision paradigm shift toward therapies transcend conventional approaches, promising breakthroughs diagnosis, treatment, prevention.
