“…AgNPs was stabilised and reduced by the phytoconstituents present in the Morinda tinctoria leaf extract. M. tinctoria leaf acetonic extract-mediated AgNPs were used to assess the larvicidal potential and it shows high mortality values of 50% against C. quinquefasciatus [139]. AgNPs mediated by M. Tinctoria possess a promising larvicidal activity against dengue vector Aedes aegypti at the stage of 3rd instar larvae and recorded 50% lethal concentration of leaf extract and M. tinctoria-mediated AgNPs showed that LC 50 was found to be 11.716 ppm.…”

The alarming effect of antibiotic resistance prompted the search for alternative medicine to resolve the microbial resistance conflict. Over the last two decades, scientists have become increasingly interested in metallic nanoparticles to discover their new dimensions. Green nano synthesis is a rapidly expanding field of interest in nanotechnology due to its feasibility, low toxicity, eco-friendly nature, and long-term viability. Some plants have long been used in medicine because they contain a variety of bioactive compounds. Silver has long been known for its antibacterial properties. Silver nanoparticles have taken a special place among other metal nanoparticles. Silver nanotechnology has a big impact on medical applications like bio-coating, novel antimicrobial agents, and drug delivery systems. This review aims to provide a comprehensive understanding of the pharmaceutical qualities of medicinal plants, as well as a convenient guideline for plant-based silver nanoparticles and their antimicrobial activity. K E Y W O R D Santimicrobial, eco-friendly, green synthesis, silver nanoparticles | INTRODUCTIONNanotechnology is a growing industry that can be used to create nanoscale structures. Nanoproducts are concerned with the approach and synthesis of particles with a diameter ranging from 1 to 100 nm. In living beings, nanotechnology is a combination of wet, dry, and computerised nanotechnology. Wet nanotechnology encompasses biological agents such as membranes, organs, and enzymes. Dry nanotechnology deals with surface science, physical, chemical properties, and the production of inorganic materials such as silicon and carbon. Modelling and simulation of complex nanometre-scale structures are part of computational nanotechnology [1]. Figure 1 depicts how these three disciplines were intertwined for optimal functionality. Nanoscale compounds can be distinguished by specific properties, opening up a wide range of applications, as well as the extension of science nanoscale discipline and research opportunities.

“…The aqueous extract of the seaweed Hypnea musciformis caused a high rate of mortality for Aedes aegypti mosquitoes. (Roni et al ., 2015) The Morinda tinctoria extract recorded the death rate of the 3rd instar larvae of Aedes aegypti mosquitoes by LC50 11.7 ppm (Kumar et al ., 2014). The ovicidal, larvicidal and repellent activities of Pemphis acidula leaf extracts were studied against Aedes aegypti and Culex quinquefasciatus .…”

Mosquitoes are a vector of dangerous diseases that kill millions of people annually. The traditional methods of control depend on the use of pesticides, which leads to the emergence of resistance against them over time, in addition to the pollution they leave in the environment and the targeting of beneficial organisms. Therefore, this study aimed to use extracts of natural products from Juniperus procera and Dodonaea viscosa plants in the control of mosquito larvae of Culex pipiens, as well as their applications in nanoparticle synthesis and effectiveness on mosquito larvae. These nanoparticles were determined and confirmed using multiple techniques, including UV–visible spectrometry, Fourier transform infrared spectroscopy and scanning electron microscopy. The IC50 values of the extracts plus silver nanoparticles were 20.871 and 105.166 ppm, a 5.03‐ and 2.17‐fold increase over the individual extracts, with IC50 values of 105.166 and 228.271 ppm, respectively. In addition, some morphological deformations were observed on the treated larvae through the stage of larval development into a pupa and the stage of emergence from a pupa into a complete insect.

“…Packaging prepared with nano sensors can also track either the internal or external circumstances of food products, vessels, and pellets. For example, Opel, which is used to make Opalfilm, containing 50-nm carbon black nanoparticles, was used as a biosensor that could change color in response to food spoilage [5][6][7][8][9][10][11][12][13].…”

Nanotechnology is new frontiers of this century. The world is facing great challenges in meeting rising demands for basic commodities(e.g., food, water and energy), finished goods (e.g., cellphones, cars and airplanes) and services (e.g., shelter, healthcare and employment) while reducing and minimizing the impact of human activities on Earth’s global environment and climate. Nanotechnology has emerged as a versatile platform that could provide efficient, cost-effective and environmentally acceptable solutions to the global sustainability challenges facing society. In recent years there has been a rapid increase in nanotechnology in the fields of medicine and more specifically in targeted drug delivery. Opportunities of utilizing nanotechnology to address global challenges in (1) water purification, (2) clean energy technologies, (3) greenhouse gases management, (4) materials supply and utilization, and (5) green manufacturing and hemistry. Smart delivery of nutrients, bio-separation of proteins, rapid sampling of biological and chemical contaminants, and nano encapsulation of nutraceuticals are some of the emerging topics of nanotechnology for food and agriculture. Nanotechnology is helping to considerably improve, even revolutionize, many technology and Industry sectors: information technology, energy, environmental science, medicine, homeland security, food safety, and transportation, among many others. Today’s nanotechnology harnesses current progress in chemistry, physics, materials science, and biotechnology to create novel materials that have unique properties because their structures are determined on the nanometer scale. This paper summarizes the various applications of nanotechnology in recent decades Nanotechnology is one of the leading scientific fields today since it combines knowledge from the fields of Physics, Chemistry, Biology, Medicine, Informatics, and Engineering. It is an emerging technological field with great potential to lead in great breakthroughs that can be applied in real life. Novel Nano and biomaterials, and Nano devices are fabricated and controlled by nanotechnology tools and techniques, which investigate and tune the properties, responses, and functions of living and non-living matter, at sizes below100 nm. The application and use of Nano materials in electronic and mechanical devices, in optical and magnetic components, quantum computing, tissue engineering, and other biotechnologies, with smallest features, widths well below 100 nm, are the economically most important parts of the nanotechnology nowadays and presumably in the near future. The number of Nano products is rapidly growing since more and more Nano engineered materials are reaching the global market the continuous revolution in nanotechnology will result in the fabrication of nanomaterial with properties and functionalities which are going to have positive changes in the lives of our citizens, be it in health, environment, electronics or any other field. In the energy generation challenge where the conventional fuel resources cannot remain the dominant energy source, taking into account the increasing consumption demand and the CO2 .Emissions alternative renewable energy sources based on new technologies have to be promoted. Innovative solar cell technologies that utilize nanostructured materials and composite systems such as organic photovoltaic offer great technological potential due to their attractive properties such as the potential of large-scale and low-cost roll-to-roll manufacturing processes
