TLDR
This review provides an overview of three main categories of nanomaterials (inorganic, carbon-based, and polymeric-based materials) used for environmental remediation.
Abstract
Environmental remediation relies mainly on using various technologies (eg, adsorption, absorption, chemical reactions, photocatalysis, and filtration) for the removal of contaminants from different environmental media (eg, soil, water, and air) The enhanced properties and effectiveness of nanotechnology-based materials makes them particularly suitable for such processes given that they have a high surface area-to-volume ratio, which often results in higher reactivity This review provides an overview of three main categories of nanomaterials (inorganic, carbon-based, and polymeric-based materials) used for environmental remediation The use of these nanomaterials for the remediation of different environmental contaminants—such as heavy metals, dyes, chlorinated organic compounds, organophosphorus compounds, volatile organic compounds, and halogenated herbicides—is reviewed Various recent examples are extensively highlighted focusing on the materials and their applications

Applications of Nanoparticles in Wastewater Treatment

TL;DR: In this paper, a review of different properties of nanoparticles contributing to water treatment and nanoadsorbents used for removal of numerous pollutants in groundwater purification is presented. But despite progress made in the development of sustainable technologies, their use has been limited, largely because of the limitations of the materials' properties, including their costs.

Negligible Particle-Specific Antibacterial Activity of Silver Nanoparticles

TL;DR: This work suggests that AgNP morphological properties known to affect antimicrobial activity are indirect effectors that primarily influence Ag(+) release, and antibacterial activity could be controlled by modulating Ag(+ release, possibly through manipulation of oxygen availability, particle size, shape, and/or type of coating.
