Scientists have investigated the possibility of employing nanomaterials as drug carriers. These nanomaterials can preserve their content and transport it to the target region in the body. In this investigation, we proposed a simple method for developing distinctive, bioderived nanostructures with mesoporous carbon nanoparticles impregnated with tungsten oxide (WO 3 ). Prior to characterizing and encapsulating WO 3 with bioderived mesoporous carbon, the anticancer drug doxorubicin (DOX) was added to the nanoparticles and examined loading and release study. The approaches for both nanoparticle production and characterization are discussed in detail. Colloidal qualities of the nanomaterial can be effectively preserved while also allowing transdermal transportation of nanoparticles into the body by forming them into green, reusable, and porous nanostructures. Although the theories of nanoparticles and bioderived carbon each have been studied separately, the combination presents a new route to applications connected to nanomedicine. Furthermore, this sample was used to study exotic biomedical applications, such as antioxidant, antimicrobial, and anticancer activities. The W-3 sample had lower antioxidant activity (44.01%) than the C@W sample (56.34%), which was the most potent. A high DOX entrapment effectiveness of 97% was eventually achieved by the C@W sample, compared to a pure WO 3 entrapment efficiency of 91%. It was observed that the Carbon/WO 3 composite (C@W) sample showed more efficacy because the mesoporous carbon composition with WO 3 increases the average surface area and surface-active locations.

“…In recognition of several uses, it is essential to comprehend the reason the Zn dopant level alters the specific surface area of the produced CuO nanostructures. Utilizing the nitrogen sorption isotherm at 77 K and the Barrett‐Joyner‐Halenda (BJH) pore size distribution, the specific surface area (SSA) and pore size distribution of the CuO and Zn‐doped CuO distinct powder samples were analyzed [41] . Figure 6 (a–j) illustrates the Brunauer, Emmett and Teller (BET) isotherm and pore size distribution plots of pure CuO and Zn‐doped CuO samples (C, Z‐1, Z‐2, Z‐3 and Z‐4).…”

Bacterial diseases are causing major health issues across the world. Recent research has revealed that the metal ion discharge of nanomaterials is extremely effective at eradicating bacterial outbreaks and resistance. Reactive oxygen species (ROS) for antibacterial functions have been produced using nanomaterials with high specific surface area, complex structural framework, and spectral properties. In this study, we thoroughly investigated the impact of Zn dopants on copper oxide (CuO) nanostructures and their nanomaterial‐based antibacterial processes. The method of production includes the formation of CuO and Zn‐doped CuO nanostructures via chemical coprecipitation. By using several characterization techniques, the as‐synthesized nanostructures were confirmed. Based on their specific surface area and surface‐active site, the different antibacterial activities of these dopants vary the antibacterial action. The antibacterial activity was evaluated using the agar well diffusion method. A significant antibacterial action was observed in the samples. In the pharmaceutical and food sectors, this CuO and its combined dopants can be a substitute for synthetic antibacterial agents.

The high surface-to-volume ratio and extraordinarily large-surface area of two-dimensional (2D) metal−organic framework (MOF) architectures have drawn particular interest for use in supercapacitors. To achieve an excellent electrode material for supercapacitors, well-defined 2D nanostructures of novel trimetallic MOFs were developed for supercapacitor applications. Multivariate MOFs (terephthalate and trimesate MOF) with distinctive nanobrick and nanoplate-like structures were successfully synthesized using a straightforward one-step reflux condensation method by combining Ni, Co, and Zn metal species in equimolar ratios with two different ligands. Furthermore, the effects of the tricarboxylic and dicarboxylic ligands on cyclic voltammetry, charge−discharge cycling, and electrochemical impedance spectroscopy were studied. The derived terephthalate and trimesate MOFs are supported with stainless-steel mesh and provide a suitable electrolyte environment for rapid faradaic reactions with an elevated specific capacity, excellent rate capability, and exceptional cycling stability. It shows a specific capacitance of 582.8 F g −1 , a good energy density of 40.47 W h kg −1 , and a power density of 687.5 W kg −1 at 5 mA cm −2 with an excellent cyclic stability of 92.44% for 3000 charge−discharge cycles. A symmetric BDC−MOF//BDC−MOF supercapacitor device shows a specific capacitance of 95.22 F g −1 with low capacitance decay, high energy, and power densities which is used for electronic applications. These brand-new trimetallic MOFs display outstanding electrochemical performance and provide a novel strategy for systematically developing high-efficiency energy storage systems.
