“…In treating wastewater, nanomaterials are utilized as adsorbents. According to various studies, nanomaterials' structural qualities including such good specificity and adsorption capability make them useful at eliminating heavy metal ions from wastewater at minimum concentrations [ 71 ]. These are excellent for the adsorption of toxic substances or other pollutants because of their elevated surface region-to-volume proportion [ 72 ].…”

Rainwater discharge and human impacts produce wastewater, which is a contaminated type of water. Sediments also discharge phosphate into the water column when there is a lack of dissolved oxygen in the water. Through the manufacturing of environmentally benign nanoparticles, nanotechnology may reduce the amount of money spent by enterprises to remediate such contaminants. Because of their improved physiological, biochemical, and biomechanical qualities, nanoparticles are getting prominence. The importance of the global wastewater dilemma is discussed in this survey. The use of nanomaterials in heavy metal remediation (HMR) and wastewater treatment is covered in this survey. This paper also discusses the benefits of nanotechnology over traditional approaches in certain fields. This survey aims to gather together many recent studies on nanoparticle production and their benefits as adsorbents in the remediation of wastewater which have been done so far. The promising role of nanotechnology in wastewater remediation is surveyed in this research, which also discusses recent developments in nanotechnology-mediated remediation methods. This survey examines the vital potential of nanotechnology in wastewater treatment, as well as recent breakthroughs in nanotechnology-mediated treatment systems.

“…This ability can be harnessed in the removal of the “physical‐world” pollutants. The application of these techniques in wastewater treatment is an important area of research [33]. Due to their advantageous characteristics such as large surface area, high adsorbability, increased reactivity, and greater surface‐to‐volume ratio, different nanomaterials and nanoparticles are being examined for the effective treatment of wastewater [34].…”

Removal of contaminants from wastewater is a big concern for the scientific community. Heavy metals are one of the major contaminants present in wastewater. Heavy metals such as Cd2+, Pb2+, Mn2+, and so forth, are highly toxic and pose a serious threat to the environment due to their nonbiodegradable nature. With the advent of nanobiotechnology, heavy metal contaminants can be mitigated with the help of nanomaterials produced by eco‐friendly methods. Specially designed bionanomaterials often exhibit properties such as increased shelf life, self‐healing nature, adaptability in different environments, and cost‐effectiveness, thus showing advantages over nanomaterials produced by physicochemical methods. Due to their high specificity and adsorption capacity, bionanomaterials can remove heavy metals present even in a very low concentration in wastewater. The use of bionanotechnology in their remediation paves a way for environmental sustainability and helps in cost reduction. This paper intends to discuss the nanobiotechnological approach for the remediation of heavy metals from wastewater. Furthermore, the paper also reviews some important nanomaterials and their potential applications in the depollution of heavy‐metal contaminated wastewater.

“…Therefore, nano-bioremediation (NBR) is one of such kind of methods, which exploits the benefits of nanomaterials together with advantages of bioremediation,received a lot of concern in the past few years. Nano-bioremediation could be defined as "NBR is the removal of environmental pollutants from contaminatedsites using nanoparticles formed by bacteria, algae, actinomycetes, fungi, andplants, by the help of nanotechnology" (Mallikarjunaiah et al 2020). NBR is a method by which nanomaterials could use in removing different contaminants from environmental matrices with biological processes or selected microbial species (Semerád et al 2020;Singh et al 2020a;Shahi et al 2021).…”

“…Therefore, there is a need for a complete knowledge of plant physiology, biochemistry and degradation of pollutants as well as a suitable assessment of probable collaborative impacts . As nanomaterials has applied to almost all fundamental disciplines including agriculture (Attia and Elsheery 2020), medicine (Saxena et al 2020), and food technology (Thangadurai et al 2020), nanomaterials also have been used in environmental remediation (Guerra et al 2018;Das et al 2019;Ken and Sinha 2020;Mallikarjunaiah et al 2020;Qian et al 2020;Agrawal and Verma, 2021;Trivedia and Bergi, 2021). The nanotechnology could be used for in situ remediation of polluted soils through the following mechanisms immobilization, Fenton and Fenton-like oxidation, photocatalytic degradation, reduction reaction and various combinations (Qian et al 2020).…”

T HE human activities include the agricultural, industrial and other activities. The agricultural sector is considered the main source for our life's supplies. However, the agricultural activities or practices might result many pollutants such as applied mineral fertilizers, pesticides, effluents from domestic and industrial sewages and vehicular emissions. Therefore, a remediation to remove or decrease the pollutants in soil and water is needed for the environment protection. This remediation has several classic strategies several years ago, but a promising and new approaches have been established particularly nano-remediation. This nano-remediation depends on the applied nanomaterials in removing pollutants from soils and water through nano-bioremediation and nano-phytoremediation. The most important nanomaterials that have potential in removing pollutants from contaminated soils and water are nano-silica, nano-zero-valent of iron, nano-sized iron sulfide particles, nano-ZnO and others. However, many challenges or open questions are still needing a justification because using nanomaterials in higher concentrations are toxic to plants and agro-environment. Are these nanomaterials stable under environmental conditions or will be converted into toxic ones or still need to be identified for sustainable nano-remediation? Is there any possibility to enter the nanomaterials or other toxic compounds the food chain through these plants? Therefore, a lot of further research is needed concerning the nano-remediation in removal the agro-pollutants.
