J. V. Vaghasiya, C. C. Mayorga-martinez, et al.

Discover the innovative world of thermosensitive magnetic nanorobots, designed for efficient water treatment. These remarkable nanorobots selectively capture harmful pollutants like arsenic and atrazine and can release them on demand, turning waste into a manageable resource. Developed by Jayraj V. Vaghasiya, Carmen C. Mayorga-Martinez, Stanislava Matějková, and Martin Pumera, this research paves the way for a cleaner and more sustainable environment.

Abstract

This paper introduces thermosensitive magnetic nanorobots (TM nanorobots) for water treatment. These nanorobots, composed of pluronic tri-block copolymer (PTBC) and iron oxide (Fe₃O₄) nanoparticles, exhibit temperature-responsive pollutant pickup and disposal. Above the critical micelle temperature (CMT), pollutants like arsenic and atrazine are trapped within the PTBC matrix. Cooling below the CMT releases the pollutants. The nanorobots demonstrate high removal efficiency and reusability, offering a promising approach for targeted pollutant removal.
