Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201405757-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A novel magnetic hydrogel</bold> is formed via the field‐directed assembly of magnetic nanomaterials during the gelation process. The novel magnetic hydrogel exhibits direction‐dependent thermogenesis in an alternating magnetic field. The specific absorption rate value in the direction along the assemblies can be 2.1‐fold as much as that in the direction normal to the assemblies while the heating rate is 6–8‐fold. Due to the anisotropic thermogenesis, the novel magnetic hydrogel also shows a direction‐dependent release of drugs that has a 3.4‐fold difference between the two directions. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgjhx62tks" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
