“…Bottom-up approaches were first explored and optimized with elemental nanoparticles of noble metals such as gold, silver, and palladium. 45,46 Later, the approaches were adapted for the synthesis of bimetallic nanoparticles, composed of two elements, starting with dual precursors. 47 Further advances in this field saw the nanoparticle synthesis of metal oxides, chalcogenides, polymers, carbon-based nanostructures, and recently doped and multicomponent versions of these materials.…”

Metal oxide semiconductors with a bandgap between 2 and 4 eV are an important class of compounds in the electronics industry and for photocatalysis. With the demand for these materials expanding rapidly, especially in the field of photocatalysis, the fabrication of nanoscale metal oxide particles, which increases the surface-to-volume ratio and thereby reduces the materials costs, is an emphasis of current research. For the purpose of photocatalysis, another important quality is the ability to absorb light efficiently. However, due to the wide bandgap of metal oxide semiconductors, the absorptions are limited to the UV region. Conveniently, a wider range of wavelengths and physical properties can be enabled by doping these metal oxide nanoparticles. Furthermore, the synthesis of doped metal oxides in nanoparticle form offers utility in an expansive array of systems, substrates, and dispersion media. However, the reliable synthesis of nanosized colloidal particles of doped metal oxides remains an ongoing challenge for materials researchers. This manuscript gives a concise overview of research conducted regarding the synthesis of visible-light-active doped metal oxide nanoparticles (NPs) and analyzes how doping impacts the optical properties, making them active in the visible to near-infrared regions. The effects of doping on applications are also summarized. Given that the most commonly doped metal oxide materials are TiO 2 and ZnO, this review highlights both anion-and cation-doped TiO 2 and ZnO nanoparticles. In addition, doped perovskite nanoparticles (e.g., BaTiO 3 and SrTiO 3 ) as well as some of the lesser studied doped metal oxide nanoparticle systems are covered. This work is intended to provide not only a broad overview of existing doped metal oxide nanoparticles but also a foundation for the development of semiconducting nanoparticle architectures for next-generation applications.

“…In addition, self-limiting self-assembly processes have been developed by regulating the growing environment [74]. Indeed, nanostructures can be naturally produced in the liquid phase during the erosion and chemical decay of organic (e.g., plant, microbes) and inorganic (e.g., clays) starting materials [193]. In these dissolution modes, the surface features and chemical modification are crucial for the formation of individual nanoparticles in the given medium.…”

Nanomaterials are materials with one or more nanoscale dimensions (internal or external) (i.e., 1 to 100 nm). The nanomaterial shape, size, porosity, surface chemistry, and composition are controlled at the nanoscale, and this offers interesting properties compared with bulk materials. This review describes how nanomaterials are classified, their fabrication, functionalization techniques, and growth-controlled mechanisms. First, the history of nanomaterials is summarized and then the different classification methods, based on their dimensionality (0–3D), composition (carbon, inorganic, organic, and hybrids), origin (natural, incidental, engineered, bioinspired), crystal phase (single phase, multiphase), and dispersion state (dispersed or aggregated), are presented. Then, the synthesis methods are discussed and classified in function of the starting material (bottom-up and top-down), reaction phase (gas, plasma, liquid, and solid), and nature of the dispersing forces (mechanical, physical, chemical, physicochemical, and biological). Finally, the challenges in synthesizing nanomaterials for research and commercial use are highlighted.

“…Moreover, the lack of actions and clear‐cut policies from the FDA are impacting the development of nanomedicines, as investors are interested only in projects that are economically secured by globally accepted rules and regulations, and they have halted the commercialization of NMs (Foulkes et al, 2020). Green NMs synthesized from biological sources represent bionanomaterials that are a perfect replacement for conventional NMs used in biomedical applications as have negligible toxicity and hence negligible adverse effects on the environment, animals, and humans (Jeevanandam, Ling, et al, 2022).…”

Nanotechnology has attracted the attention of researchers from different scientific fields because of the escalated properties of nanomaterials (NMs) compared with the properties of macromolecules. NMs can be prepared through different approaches involving physical and chemical methods. The development of NMs through plantbased green chemistry approaches is more advantageous than other methods from the perspectives of environmental safety, animal, and human health. The biomolecules and metabolites of plants act as reducing and capping agents for the synthesis of metallic green NMs. Plant-based synthesis is a preferred approach as it is not only cost-effective, easy, safe, clean, and eco-friendly but also provides pure NMs in high yield. Since NMs have antimicrobial and antioxidant potential, green NMs synthesized from plants can be used for a variety of biomedical and environmental remediation applications. Past studies have focused mainly on the overall biogenic synthesis of individual or combinations of metallic NMs and their oxides from different biological sources, including microorganisms and biomolecules.Moreover, from the viewpoint of biomedical applications, the literature is mainly focusing on synthetic NMs. Herein, we discuss the extraction of green molecules and recent developments in the synthesis of different plant-based metallic NMs, including silver, gold, platinum, palladium, copper, zinc, iron, and carbon. Apart from the biomedical applications of metallic NMs, including antimicrobial, anticancer, diagnostic, drug delivery, tissue engineering, and regenerative medicine applications, their environmental remediation potential is also discussed. Furthermore, safety concerns and safety regulations pertaining to green NMs are also discussed.
