“…52 However, such enormous E-factor values relate to the methods of fabrication of nonfunctionalized and nontargeted nanoparticles (e.g., gold, silica, etc.). 53 In contrast, STF demonstrates an overwhelmingly low environmental impact with its E-factor value of 16.9 (the details of the calculation are shown in the Supporting Information). Such a comparison demonstrates that STF is a unique technique to produce targeted nanoparticles with an extremely low environmental impact.…”

Protein-based nanoparticles are promising candidates to be used as nanomedicine due to their high biocompatibility. On the other hand, functional nanoagents are fabricated using complex, nonscalable, and environmentally unfriendly procedures. An urge to meet multiple biomedical and industrial requirements highlights a need to find a universal, ecofriendly, and flexible synthetic strategy of functional nanoagent engineering. Here, we show a green, ultrafacile, and size-controlled synthesis (swift thermal formation; STF) of monodisperse immunoglobulin-based nanoparticles. The synthesis allows the fabrication of hybrid nanoparticles as well. We show that the nanoparticles retain the specificity of immunoglobulins and can target malignant cells. In addition, we demonstrate that the nanoparticles are biocompatible and applicable in vivo. Tunability, ease, and sustainability of the synthesis may turn the targeted nanoagent design into a routine procedure. This ready-to-use solution could assist a broad spectrum of biomedical applications, e.g., imaging and therapy.

At present, nanotechnology is a significant research area in different countries, owing to its immense ability along with its economic impact. Nanotechnology is the scientific study, development, manufacturing, and processing of structures and materials on a nanoscale level. It has tremendous application in different industries such as construction. This study discusses the various progressive uses of nanomaterials in concrete, as well as their related health risks and environmental impacts. Nanomaterials such as nanosilica, nano-TiO2, carbon nanotubes (CNTs), ferric oxides, polycarboxylates, and nanocellulose have the capability to increase the durability of buildings by improving their mechanical and thermal properties. This could cause an indirect reduction in energy usage and total expenses in the concrete industry. However, due to the uncertainties and irregularities in size, shape, and chemical compositions, some nanosized materials might have harmful effects on the environment and human health. Acknowledgement of the possible beneficial impacts and inadvertent dangers of these nanosized materials to the environment will be extremely important when pursuing progress in the upcoming years. This research paper is expected to bring proper attention to the probable effects of construction waste, together with the importance of proper regulations, on the final disposal of the construction waste.

“…The invention of several spectroscopic techniques accelerated research and innovations in the field of nanotechnology [108]. In general, nanomaterials are classified into distinct aspects, such as dimensionality, morphology, state, and chemical composition [108][109][110], as shown in Figure 1. In recent years, research related to nanostructured materials has been looking for ways to innovate through synthetic routes that are environmentally friendly, as there is substantial concern with nanomaterials being considered toxic in nature [111].…”

Conversion of Plastic Waste into Supports for Nanostructured Heterogeneous Catalysts: Application in Environmental Remediation

et al. 2021

Plastics are ubiquitous in our society and are used in many industries, such as packaging, electronics, the automotive industry, and medical and health sectors, and plastic waste is among the types of waste of higher environmental concern. The increase in the amount of plastic waste produced daily has increased environmental problems, such as pollution by micro-plastics, contamination of the food chain, biodiversity degradation and economic losses. The selective and efficient conversion of plastic waste for applications in environmental remediation, such as by obtaining composites, is a strategy of the scientific community for the recovery of plastic waste. The development of polymeric supports for efficient, sustainable, and low-cost heterogeneous catalysts for the treatment of organic/inorganic contaminants is highly desirable yet still a great challenge; this will be the main focus of this work. Common commercial polymers, like polystyrene, polypropylene, polyethylene therephthalate, polyethylene and polyvinyl chloride, are addressed herein, as are their main physicochemical properties, such as molecular mass, degree of crystallinity and others. Additionally, we discuss the environmental and health risks of plastic debris and the main recycling technologies as well as their issues and environmental impact. The use of nanomaterials raises concerns about toxicity and reinforces the need to apply supports; this means that the recycling of plastics in this way may tackle two issues. Finally, we dissert about the advances in turning plastic waste into support for nanocatalysts for environmental remediation, mainly metal and metal oxide nanoparticles.
