New graphene based nanobotes may be an effective solution for marine pollution which is getting worse over the last few decades. Contaminants such as plastics and heavy metals present an obstacle to both marine life and the humans who depend on them. These underwater soldiers have been said to remove up to ninety-five percent of the lead in a water source within an hour. Nanobots are made to collect heavy metals using a magnetic field in hopes of cleaning up the ocean. Because of its effectiveness, nanotechnology is becoming utilized more against contaminants. A nanobot is self-propelled and tinier than a human hair. Many praise the microbots for being a remediation system that can get the work done without leaving behind any contaminants of its own. Experts state that the development of the nanobot is proof that industry is moving in a way beneficial to water sources of the world, and hopefully will continue to do so. As of now, they are being controlled indirectly by a magnetic field created by engineers but soon enough, it is possible that these nanobots become completely autonomous and clean up the mess we have made in our waterways.
