Über dieses Buch

This book provides essential information on the role of phytonanotechnology in the removal of environmental pollutants and covers recent advances in experimental and theoretical studies on plant-derived nanoparticles. It also discusses their current and potential applications and challenges.The combination of nanotechnology and phytoremediation, which is called phytonanotechnology, have the potential to remove contaminants from the environment or degrade them. The efficiency of contaminant removal can be improved by combining both methods as they are complementary to each other.Phytonanotechnology offers the advantages of increased bioavailability, prolongation of heavy metal absorption time, and multiple metal removal, all contributing to improved efficacy and decreased toxicity in plants and surroundings. Therefore, there is immense scope for nature-derived molecules to be formulated into nanotechnology-based phytoremediation approaches targeting the specific heavy metal removal from effluents and surroundings. This encourages research initiatives to synthesize more phytonanotechnology based uptake plant systems with high efficiency. Efficient formulation targeting strategies and the evaluation of targeting efficiency of phytonanotechnology, conforming to international standards of their toxicology and biocompatibility, could pave the way for heavy metal uptake and removal by plant-based systems.This book serves as a valuable resource for postgraduate students, environmental scientists and materials scientists in academia and corporate research.

Plant Synthesized Nanoparticles for Dye Degradation
Abstract
Dyes are mostly used in many industries such as textile, food, leather, cosmetics, pharmaceuticals, paper industry, etc. Industrial dyes when released spoil the ecosystem, they are hazardous to aquatic life, animals, and mankind. So there is a need to degrade the dyes to reduce the toxicity present in them. Among various methods available for the degradation of dyes the best method is to use nanoparticles synthesized from plants because it is promising, eco-friendly, and nontoxic. Plant sources act as reducing agents for nanoparticles synthesis which will replace the toxic chemicals. And how effective they are in the degradation of dye and the mechanism of action of the degradation of dye that will reduce the toxicity is discussed. It also provides information about how this dye degradation helps in reducing pollution.

Plant-Mediated Green Synthesis of Nanoparticles for Photocatalytic Dye Degradation
Abstract
Due to advancements in industrialization, water pollution has become a major critical issue since it directly affects the quality of global water resources, human beings, organisms, plants, and animals. The main reason for the water pollution is unscientific management of industrial waste and population explosion. Water contamination and treatment technologies are two major topics of interest; water treatment technologies are also being developed in several ways. However, developing an economically feasible and highly efficient water treatment approach for all chemical water pollutants is ongoing. Photodegradation of this effluent is one of the best and simplest ways to convert or degrade contaminants or pollutants into a less harmful or non-toxic substance. Therefore, developing environmentally benign photocatalysts with remarkable stability and recyclability by a cost-effective and green method is becoming a prime requirement. Metal oxide nanomaterials are widely used as efficient photocatalysts due to their outstanding and unique optical properties. Metal oxides can be synthesized by various methods such as electrochemical, Sono-chemical, sol-gel, hydrothermal, polyol, and coprecipitation. However, the plant-mediated route is environmentally benign and straightforward. Hence, in this chapter, we have reviewed plant-mediated metal and metal oxide (M/MO) photocatalyst to dyes degradation. The chapter also focuses on the plausible mechanistic explanation of the photodegradation process. Lastly, we have explained the need for further developments to achieve a highly efficient and stable photocatalyst.

Application of Nanotechnology in Plant Secondary Metabolites Production
Abstract
After decades of research, the crucial role of primary metabolites as necessary compounds for the basic life functions and secondary metabolites as essential compounds for the survival and adapting to the environment during abiotic and biotic stresses conditions were deduced. Various secondary metabolites like alkaloids, flavonoids, phenolic acids, steroids, glycosides, tannins, resins, terpenoids, etc., are extensively studied for their commercial applications in cosmetics, pharmaceuticals, nutraceuticals, and food industries. Currently, there is a vast scope in enhancing plant secondary metabolite production to obtain high yields appropriate for commercial use. Different elicitation methods like biotic (rhizobacteria and fungus) and abiotic (light, salt, metals, temperatures, and drought) elicitors are used to increase secondary metabolite production. Lately, phytonanotechnology has been gaining more attention in plant biotechnology to develop efficient methods to increase plant growth and enhance the production of plant secondary metabolites. The framework of this chapter summarizes the impact of nanomaterials in promoting the production of secondary plant metabolites and their applications. Based on available scientific reports, the knowledge of nanomaterial–plant interactions, mechanism, factors governing these cross-talks, and their biological significance are explored here. Additionally, to improve the influence of nanoparticles on the production of valuable pant secondary metabolites, future directions and strategies for developing formulations are discussed.

Applications of Nanotechnology in Preservation and Development of the Plants: A Look Back
Abstract
In this era of global warming, agrarian strategies across the world are plagued with a slew of issues. Improved nano-engineering is a useful technique for increasing agricultural output and ensuring long-term sustainability in the pursuit of rural livelihoods. Nanotechnology aids in the improvement of agricultural output by boosting input efficiency and reducing relevant losses. Fertilisers and insecticides have a smaller specific surface area than nanomaterials. Nanoparticles also enable regulated, forum nutrition delivery with increased crop protection as distinctive drivers of industrial chemicals. Whilst nanotechnology’s rapid advancement in biomedical sciences has transformed therapeutic and diagnostic techniques in recent years, understanding nanoparticle–plant interactions, such as absorption, mobility, and accumulation, is still in its infancy. Because of their direct and intentional use in the specific administration and management of efforts, nanotools, such as nanobiosensors, enable the growth of high-tech farming (fertilisers, pesticides, herbicides). Nonosensors that combine biology and nanotechnology have substantially enhanced their ability to perceive and recognise environmental circumstances or impairments, with the ultimate goal of improving plant defence and/or enhancing photosynthetic activity, as well as farming methods. Humans also feel that multidisciplinary collaboration approaches will be crucial in narrowing the research gaps in plant nanotechnology and increasing the practice of NMs in farming and plant science research a broad sense.

Bioremediation of Heavy Metal Contaminated Sites Using Phytogenic Nanoparticles
Abstract
Heavy metals (HMs) accumulate in milieu due to various human activities that persist leading to biomagnification in food chains and cause unpleasant effects on human health and environment. Pollutants such as organic matter and HMs are remediated traditionally by chemical precipitation, electrochemical treatment, adsorption, reverse osmosis, ion exchange, coagulation, and photo-catalyzation, remained ineffective. Use of nanomaterials conjugated with various compounds showed significant reduction in several contaminated sites. However, existing implication of nanotechnology works with nanoparticles (NPs) synthesis majorly involved the use of chemical raw materials and physical methods which are relatively toxic and unstable. Aforesaid difficulties made researchers and entrepreneurs to reconnoitre effective, newer, and novel synthesis approaches for the replacement over older version. During the past decade, to overcome these issues plant-derived NPs are extensively used because of its less cost, efficiency, and eco-friendly in nature. Hence, advanced alternative technology like phytoremediation using nanomaterials with innovative techniques has been a boon for HM remediation. Efficiency of green synthesized NPs is based on redox reactions which makes metals stable facilitated by flavonoids and polyphenols responding to HM-stress. Several metal complexation processes are known to produce phytochelatins or other metal-chelating peptides helping the bioremediation of HMs. Current chapter throws light on adaptive mechanism employed by NPs coupled with plant or microbial extracts in overcoming the HM stress. Furthermore, here we also focus on the possible mechanism and interaction between NPs and HM in minimizing severity of polluted sites with many examples.

Abstract
Naturally engineered nanomaterials in recent times have myriad potential in different fields. Moreover, green derived nanoparticles (NPs) encourage broader implementation for wider applications. Amongst many metals, copper and its oxide-based nanoparticles (CuONPs) have increased utmost consideration owing to its specific characteristics, abundance, and cost-effectiveness. Major setback of chemical and physical methods of synthesising CuONPs involves high cost along with environmental hazards. Aforementioned challenge compelled researchers to explore green synthesised CuONPs that is much cheaper, efficient, economically beneficial, non-toxic, and eco-friendly. Existing plant-based CuONPs have potential efficiency to enhance the toxic effects against the plant pathogens and combating environmental pollution through bioremediation. Several extracts of plant derivatives have been used for the synthesis of CuONPs such as Azadirachta indica, Hibiscus rosa-sinensis, Murraya koenigii, Moringa oleifera, Tamarindus indica, Eclipta prostrate, Olea europaea, etc. Microbes as cell factories are more efficiently used as NPs compared to larger plants such as, green algae Botryococcus braunii, brown algae Macrocystis pyrifera, Bifurcaria bifurcate etc. Bio-based CuONPs have been applied in numerous fields such as pharmaceutical, molecular biology, bioremediation, cosmetics, textiles etc. Several of them also employed in dye degradation, water treatment, food preservation, Photovoltaic devices, solar energy conversions, and field emission emitters. However, as in clinical setup due to their efficacy these are exclusively used as anticancer, antimicrobial agents. Further, their high antioxidant potential renders them as an invaluable tool for biomedical devices.

Photocatalytic Degradation of Dye from Various Metal/Metal Oxides Derived from Diverse Plants
Abstract
Toxic dyes are rapidly becoming a big issue in terms of water/soil pollution, as they have an effect the purity of world water bodies, human health and creatures. Unscientific management of industrial dye waste is the primary cause of water pollution. The dyes that come from industries kept a lot of impact on aquatic ecosystems. The ingestion of these dyes through food, vegetables and fish has long-term negative consequences, making them toxic to human health. Therefore, it is a pressing necessity to obtain a simple, quick and low-cost technique for detecting, identifying and purifying these dyes in aqueous medium or from any other source. Various processes, such as sorption, photocatalytic degradation and conversion, can be used to handle industrial waste dyes. Compared to sorption and conversion, photocatalytic degradation has various advantages, including environmental protection and total pollution degradation. Photocatalytic degradation is possible with both metal and non-metal nanoparticles. There are numerous papers on the use of CNTs, ZnO, TiO2 and other nanoparticles for dye degradation, but the preparation of this both metal and non-metal are required harsh reaction condition and which cause a harmful impact on the environment. The production of nanoparticles using various plant extracts (phyto-nanoparticles) has a cleaner approach. To use of such nanoparticles in the dye degradation process has more impact.
