Ammonium persulfate is a widely used reagent in biochemistry and molecular biology for the preparation of polyacrylamide gels. APS forms oxygen free radicals in aqueous solution by a base-catalyzed mechanism. Other applications of APS include its use as a reducer and retarder in photography, the manufacture of aniline dyes, electroplating, the decolorizing and deodorizing of oils. A protocol on the APS-mediated modification of polypropylene membranes with polyaniline has been published. APS has been used to prepare biodegradable macroporous hydrogels for application as crosslinkable biomaterials.
