Magnetic hydrogel nanocomposites and composite nanoparticles form a class of soft materials with remote
controllable properties that have attracted great attention due to their potential use in diverse applications. These include
medical applications such as controlled drug delivery, clinical imaging and cancer hyperthermia and ecological applications
as well, such as wastewater treatment. The present review provides an overview of the patents disclosed and research
work developed in the last decade on magnetic hydrogel nanocomposites and magnetic hydrogel composite nanoparticles
envisaging the above mentioned applications. In this context, recent patented advances on chemical methods for the
preparation of bulk hydrogel nanocomposites and composite nanoparticles will be reviewed.
