CuO NPs were planned to synthesize using Abutilon indicum (A. indicum) leaf aqueous extract as an ecofriendly source without any harmful chemicals like other physio‐chemical methods. The ecofriendly synthesized shape controlled CuO NPs is further processed for several characterization tools to identify the morphology and its physical nature. Synthetic methodology was optimized using RSM technique. The characterization output results in crystalline rod shaped CuO NPs with 23±2 nm. Further, CuO NPs were screened for degradation study against harmful azo dye. The results indicates that the higher degradation rate in both the extract and synthesized CuO NPs, around 95.48 % degradation of dye using CuO NPs was identified using Pseudo first order reaction kinetics are being clearly stated in this manuscript. Furthermore, examination of CuO NPs in the direction of photocatalytic behaviour was optimized through taguchi methodology.

“…Nanotechnology and nanoscience refers to the improvement, advancement or application of atomic/molecular structures with at least one dimension that is in the nanoscale range (1~100 nm) with variable composition, shape/morphology, size, or surface properties [21][22][23][24]. Over the decades, NPs/nanocarriers have been utilized in a diversity of new pharmaceutical applications, namely effective delivery of drugs to the targeted sites without exposing the healthy tissue cells, sensitive imaging to detect viral illnesses at early stages, and crossing these barriers (e.g., the epithelial/endothelial, immunological, or cellular barriers) to deliver nano-therapeutic molecules or nanovaccines to specific diseased organs or cell tissues as well as to interact with biomolecules in the blood or within organ tissues.…”

Viral infections have recently emerged not only as a health threat to people but rapidly became the cause of universal fatality on a large scale. Nanomaterials comprising functionalized nanoparticles (NPs) and quantum dots and nanotechnology-associated innovative detection methods, vaccine design, and nanodrug production have shown immense promise for interfacing with pathogenic viruses and restricting their entrance into cells. These viruses have been scrutinized using rapid diagnostic detection and therapeutic interventional options against the caused infections including vaccine development for prevention and control. Coronaviruses, namely SARS-CoV, MERS-CoV, and SARS-CoV-2, have endangered human life, and the COVID-19 (caused by SARS-CoV-2) outbreak has become a perilous challenge to public health globally with huge accompanying morbidity rates. Thus, it is imperative to expedite the drug and vaccine development efforts that would help mitigate this pandemic. In this regard, smart and innovative nano-based technologies and approaches encompassing applications of green nanomedicine, bio-inspired methods, multifunctional bioengineered nanomaterials, and biomimetic drug delivery systems/carriers can help resolve the critical issues regarding detection, prevention, and treatment of viral infections. This perspective review expounds recent nanoscience advancements for the detection and treatment of viral infections with focus on coronaviruses and encompasses nano-based formulations and delivery platforms, nanovaccines, and promising methods for clinical diagnosis, especially regarding SARS-CoV-2.

“…Characterization is relevant in any study in order to guarantee reproducible synthesis of the NPs of interest. Many techniques are currently available for developing analytical methods for NPs characterization purposes since these possess unique physical, chemical, and mechanical properties from bulk solids and molecules[96][97][98].Nanomaterials have a large surface area to volume ratio, which differs greatly from the macroscopic materials[99,100]. The physicochemical properties such as size distribution, morphology, surface properties, chemical composition, kinetic behavior, stability, and interactions with other compounds exhibited by AuNPs, AgNPs, and NPs in general, depend on factors like surfactant additives, reactant concentrations, temperature, and solvent, as previously discussed.…”

Currently, metal nanoparticles have varied uses for different medical, pharmaceutical, and agricultural applications. Nano-biotechnology combined with green chemistry has great potential for the development of novel and necessary products that benefit human activities, while encourages the reduction of hazardous reagents for nanoparticle production. Green chemistry has an important role due to its contribution to unconventional synthesis methods of gold and silver nanoparticles from plant extracts, which have exhibited antimicrobial potential among other outstanding properties. Biodiversity-rich countries need to collect and convert knowledge from biological resources into processes, compounds, methods, and tools, which need to be achieved along with sustainable use and exploitation of biological diversity. Therefore, this review focuses on the importance of metal nanoparticles, the use of plant extract for their synthesis as well as other available methods, and the relevant antimicrobial activity that can be exploited in a sustainable model of agricultural management through a modern nanotechnological approach.
