Abstract

<abstract abstract-type="toc"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <graphic position="anchor" id="ga" xlink:href="ark:/27927/pgj40w109v" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" />Graphene–nanometal enzymatic biosensors were prepared using hydrogels composed of chitosan, poly-<italic>N</italic>-isopropylacrylamide, silk fibroin, or cellulose nanocrystals. The comparative study investigated electroactive surface area, charge transfer, response time, limit of detection, and sensitivity toward alcohols.</p> </abstract>
