Nanoparticles have a wide range of applications in various fields such as cosmetics, pharmaceuticals, and agrochemicals. Synthesis of nanoparticles using plant extract is a very efficient, cost-effective, useful, and environmentally friendly method. A plant extract acts as a reducing agent in the formation of nanoparticles. Catharanthus roseus is one of the potential plants for biosynthesis of nanoparticles due to its easy availability. In the present study, the Catharanthus roseus plant extract was used to synthesize iron nanoparticles. UV-vis spectroscopy, DLS, and FTIR were performed for characterization of synthesized nanoparticles. Further antibacterial and dye degrading properties of synthesized iron nanoparticles have been investigated. It was found that Catharanthus roseus-synthesized iron nanoparticles showed antibacterial activity against E. coli and dye degradation activity against methyl orange dye.

“…Composite nanoparticles are multiphasic in nature such that one of their phases can combine with other similar or dissimilar nanoparticles in bulk, complex formations, e.g., a gold nanoparticle in composition with ceramic or a polymer. Carbon-based nanoparticles consist of fullerenes, nanotubes, and nanofibers found in generally two-dimensional morphological structures [ 122 – 124 ].…”

Today, environmental contamination is a big concern for both developing and developed countries. The primary sources of contamination of land, water, and air are extensive industrialization and intense agricultural activities. Various traditional methods are available for the treatment of different pollutants in the environment, but all have some limitations. Due to this, an alternative method is required which is effective and less toxic and provides better outcomes. Nanomaterials have attracted a lot of interest in terms of environmental remediation. Because of their huge surface area and related high reactivity, nanomaterials perform better in environmental clean-up than other conventional approaches. They can be modified for specific uses to provide novel features. Due to the large surface-area-to-volume ratio and the presence of a larger number of reactive sites, nanoscale materials can be extremely reactive. These characteristics allow for higher interaction with contaminants, leading to a quick reduction of contaminant concentration. In the present review, an overview of different nanomaterials that are potential in the remediation of environmental pollutants has been discussed.

“…Although benefits of these engineered nanoparticles (ENPs) are well recognised in many industries, more attention is needed on potential toxicity and its adverse effects [19]. Nanotechnology can be applied in a number of fields including medicine, agriculture, food science, food technology, recreation, and civil engineering [20][21][22]. There is exciting potential of nanotechnology in these areas, and some applications are already of great benefit to industries and consumers.…”

Nanotechnology recently emerged among the most exciting science-related innovations. Nanotechnology-produced metal nanoparticles got a lot of attention. This is emerging as a rapidly developing field due to its effective applications that targeted the manufacturing of new materials at the nanoscale level. There is considerable interest in the application of nanomaterials in many areas of industry including agrifood and biomedical products. In the agrifood area, nanomaterials have benefits in diverse areas which include fertilizers, herbicides, pesticides, sensors, and quality stimulants, among other food processing, food packaging, and nutraceuticals to improve nutritional value. These applications in agriculture result in enhanced quality and crop yield, reduction in pollution caused by various chemicals, etc. In the pharmaceutical area, nanomaterials are claimed to ameliorate drug safety and efficacy, as well as bioavailability. They are utilized for targeting various drugs to a specific location in the body. However, there are also concerns that some nanoparticles may have adverse effects on human health. These include titanium dioxide, copper oxides, and other nanomaterials which lead to liver damage, skin damage, lung damage, and various other human health-related problems. This review is aimed at presenting a briefing on the state of the art in the application of nanotechnology in food and human nutrition and drug administration, consumer attitudes, and their challenges and opportunities with future perspectives.
