Micro/Nanobots for Wastewater Remediation

Abstract

Nowadays, balancing industrialization and environmental sustainability is one of the major challenges facing by developing nations. Numerous pollutants such as electronics products and heavy metals have polluted the ecosystem and water resources. The wastewater industries are facing many new challenges that are complicating the long-term planning decisions. Thus, there is a need to switch to smart remediation system where the removal of pollutants can be achieved without producing contamination. Nanotechnology can add significant improvement to various methods including pollution prevention, remediation and monitoring by playing an imperative role. According to recent survey, micro/nanobots can be used to remove heavy metals when deployed in industrial wastewater in more effective and economical way. This review focuses on recent advancements and challenges in micro/nanobots technology for wastewater remediation.
