Bioinorganic Nanoparticles for the Remediation of Environmental Pollution: Critical Appraisal and Potential Avenues

Abstract

Nowadays, environmental pollution has become a critical issue for both developed and developing countries. Because of excessive industrialization, burning of fossil fuels, mining and exploration, extensive agricultural activities, and plastics, the environment is being contaminated rapidly through soil, air, and water. There are a variety of approaches for treating environmental toxins, but each has its own set of restrictions. As a result, various therapies are accessible, and approaches that are effective, long-lasting, less harmful, and have a superior outcome are extensively demanded. Modern research advances focus more on polymer-based nanoparticles, which are frequently used in drug design, drug delivery systems, environmental remediation, power storage, transformations, and other fields. Bioinorganic nanomaterials could be a better candidate to control contaminants in the environment. In this article, we focused on their synthesis, characterization, photocatalytic process, and contributions to environmental remediation against numerous ecological hazards. In this review article, we also tried to explore their recent advancements and futuristic contributions to control and prevent various pollutants in the environment.

Can bacteria and carbon-based nanomaterials revolutionize nanoremediation strategies for industrial effluents?

“…The evolution of nanobioremediation hinges on creating new nanomaterials with enhanced features and biocompatibility, emphasizing the need for safety standards and responsible use. Understanding the biopersistence of nanomaterials is key to addressing environmental concerns and supporting the safe use of nanotechnology (Devasena et al, 2022;Vineeth Kumar et al, 2022;Rahman et al, 2023;Chávez-Hernández et al, 2024a). Despite its potential, addressing ecological issues remains a priority to ensure the responsible progression of technology.…”

A review of etching methods and applications of two-dimensional MXenes

“…The electrode material of lithium-ion batteries is mainly transitioning metal nitrides; however, the actual lithium resources are highly limited, which limits its large-scale power use. Sodium ion batteries and potassium ion batteries have become the hope for future energy storage systems due to their abundant resources and low costs, but they face enormous challenges in electrode materials [97,98]. MXenes, due to its large surface area and adjustable interlayer spacing, has become a rising star in electrode materials in the energy storage world, with immeasurable development prospects in sodium and potassium storage [99].…”

Nanobiohybrids for pollution control and resource recovery

“…This not only saves energy but also conserves valuable resources. By utilizing highly selective membranes, adsorbents, and paramagnetic materials, nanobiotechnology presents key opportunities for recovering nutrients not only within the agri-food value chain but also from various other sources such as wastewater, leachates, and runoff (Rahman et al, 2023).…”
