In the current study, a simple, environmentally friendly, and cost-effective reduced graphene oxide-gold nanoparticle (rGO-AuNP) nanocomposite was successfully phytosynthesized using aqueous leaf extract of common weed found on Nile banks, Persicaria salicifolia, for first time. The phytosynthesis rGO-AuNPs confirmed via color transformation from brown to black as well throughvarious techniques such transmission electron microscopy (TEM) Raman spectroscopy. Two UV-vis peaks at 275 530 nm were observed with typical particle size mostly spherical AuNPs 15-20 nm. However, other shapes occasionally detected including rods, triangles, rhomboids. Existing phytoconstituents flavonoids glycosides in plant suggested be responsible rGO-AuNPs. excellent catalytic efficacy against MB degradation confirmed, high antibacterial efficiency Escherichia coli Klebsiella pneumonia also confirmed. Promising antioxidant performance proved. Furthermore, it concluded that acquired higher than synthesized same all studied applications.

The enzyme-mediated elevation of reactive oxygen species (ROS) at the tumor sites has become an emerging strategy for regulating intracellular redox status anticancer treatment. Herein, we proposed a camouflaged bionic cascaded-enzyme nanoreactor based on Ti3C2 nanosheets combined enzyme dynamic therapy (EDT), phototherapy and deoxygenation-activated chemotherapy. Briefly, glucose oxidase (GOX) chloroperoxidase (CPO) were chemically conjugated onto nanosheets, where drug tirapazamine (TPZ) was also loaded, Ti3C2-GOX-CPO/TPZ (TGCT) embedded into nanosized cancer cell-derived membrane vesicles with high-expressed CD47 (meTGCT). Due to biomimetic camouflage overexpression, meTGCT exhibited superior immune escape homologous targeting capacities, which could effectively enhance preferential internalization. Once internalized cells, cascade reaction GOX CPO generate HClO efficient EDT. Simultaneously, additional laser irradiation accelerate enzymic-catalytic rate increase generation singlet (1O2). Furthermore, local hypoxia environment depletion by EDT would activate deoxygenation-sensitive prodrug Consequently, exhibits amplified synergistic therapeutic effects phototherapy, chemotherapy inhibition. This intelligent provides promising approach achieve concurrent significant antitumor therapy.
