Currently, I am working on design & synthesis of self-assembled magnetic nanoparticle-polymer nano-cluster for water remediation application. Increasing population, rapid urbanization, and continuous industrial growth put a large stress on the demand for clean water. Magnetic nanoparticles are very well suited for water purification and waste water treatment owing to their unique and varied properties such as large specific surface area which render them as excellent adsorbents, catalysts, and sensors for water remediation application, To benefit from the aforementioned features, typically pollutant are been exposed to freely suspended nanoparticles follows with the recollection of the particles by an magnetic field supplied externally , the exposure of freely suspended nano particles poses significant unknown risk in term of toxicological impact. Hence, surface functionalization of the magnetic nanoparticles with polymer through self-assembly mode of action could be an attractive option to minimize direct exposure of the nanoparticles to the environment while serve dual-function namely magnetic and catalytic properties. The overall aim of this research is to synthesis self-assembled magnetic nanoparticle-polymer nano-cluster for environmental application. The characterization of the magnetophoretic behaviour and colloidal stability of the nano-cluster with surface functionalization will be studied. Validation of inter-particle interaction of polymer-magnetic nanoparticles through mathematical models will be investigated and its feasibility on the model system such as heavy metals/dyes will be evaluated. It is envisaged, enhanced understanding on the behaviour of this self-assembly hybrid nanoparticles-polymer will be obtained by the end of the study.
