“…Zeta potentials for the V-2 and C@V samples are −13.15, and −13.91 mV, respectively. Since the C@V in particular has a lower value of the zeta potential in comparison to the V-2 sample, which makes it more stable as revealed in Table …”

Nanocarriers have attracted considerable interest due to their prospective applications in the delivery of anticancer medications and their distinct bioactivities. Biogenic nanostructures can be effective nanocarriers for delivering drugs as a consequence of sustainable and biodegradable biomassderived nanostructures that perform specific functions. In this case, a vanadium oxide (V 2 O 5 ) and mesoporous carbon@V 2 O 5 (C@V) composite was developed as a possible drug delivery system, and its bioactivities, including antioxidant, antibacterial, and anticancer, were investigated. Doxorubicin (DOX), an anticancer drug, was introduced to the nanoparticles, and the loading and release investigation was conducted. Strong interfacial interactions between mesoporous carbon (MC) and V 2 O 5 nanostructures have been found to improve performance in drug loading and release studies and bioactivities. After incubation, the potent anticancer effectiveness was seen based on C@V nanocomposite. This sample was also utilized to research potential biomedical uses as an antioxidant, antibacterial, and anticancer. The most effective antioxidant, the C@V sample (61.2%), exhibited a higher antioxidant activity than the V-2 sample (44.61%). The C@V sample ultimately attained a high DOX loading efficacy of 88%, in comparison to a pure V 2 O 5 sample (V-2) loading efficacy of 80%. Due to the combination of mesoporous carbon and V 2 O 5 , which increases specific surface area and surface sites of action as well as the morphology, it proved that the mesoporous carbon@V 2 O 5 composite (C@V) sample demonstrated greater efficacy.

“… Another potential method of action includes membrane function; metallic nanoparticles have a positively charged surface that allows them to interact with negatively charged bacterium membranes, enabling them to attach to various cell structures and leading to chemical interaction. The electrostatic interaction occurs between positively charged metallic nanoparticles and negatively charged bacteria on the surface and charged in cell morphology, leading to growth inhibition ROS are a species of oxygen that can damage the cell membrane, DNA, and cellular protein, which leads to cell death. , ROS are produced when oxygen enters undersized reduction states, which may be attributed to the formation of oxidative stress by the superoxide anion (O 2 •– ), hydrogen peroxide (H 2 O 2 ), and the hydroxide radical (OH • ), which leads to the formation of H 2 O 2 and further damages the DNA as well as proteins in bacteria. …”

In recent years, inorganic metal nanoparticle fabrication by extraction of a different part of the plant has been gaining more importance. In this research, cellulose-mediated Ag nanoparticles (cellulose/Ag NPs) with excellent antibacterial and antioxidant properties and photocatalytic activity have been synthesized by the microwave-assisted hydrothermal method. This method is a green, simple, and low-cost method that does not use any other capping or reducing agents. X-ray diffraction (XRD), Fourier transform infrared (FTIR), field emission scanning microscopy (FESEM), transmission electron microscopy (TEM), energy-dispersive X-ray (EDX), and UV−visible spectroscopic techniques were used to investigate the structure, morphology, as well as components of the generated cellulose/Ag NPs. In fact, XRD results confirm the formation of the face-centered cubic phase of Ag nanoparticles, while the FTIR spectra showed that the synergy of carbohydrates and proteins is responsible for the formation of cellulose/Ag NPs by the green method. It was found that the green-synthesized silver nanoparticles showed good crystallinity and a size range of about 20−30 nm. The morphology results showed that cellulose has a cavity-like structure and the green-synthesized Ag NPs were dispersed throughout the cellulose polymer matrix. In comparison to cellulose/Ag NPs and Ag nanoparticles, cellulose/Ag NPs demonstrated excellent antibacterial activity, Proteus mirabilis (MTCC 1771) possessed a maximum inhibition zone of 18.81.5 mm at 2.5 g/mL, and Staphylococcus aureus (MTTC 3615) had a minimum inhibition zone of 11.30.5 mm at 0.5 g/mL. Furthermore, cellulose/Ag NPs also exhibited a significant radical scavenging property against the DDPH free radical, and there was a higher degradation efficiency compared to pure Ag NPs against Rhodamine B as 97.38% removal was achieved. Notably, cellulose/Ag NPs remarkably promoted the transfer and separation of photogenerated electron−hole (e − /h + ) pairs, thereby offering prospective application of the photodegradation efficiency for Rhodamine B (RhB) as well as antibacterial applications. With the findings from this study, we could develop efficient and environmentally friendly cellulose/Ag nanoparticles using low-cost, environmentally friendly materials, making them suitable for industrial and technological applications.
