Activation with Divinylsulfone

The introduced groups can be further modified and activated, e.g. with carbodiimide or divinylsulfone chemistry, which enables the surface to bind to e.g. amino groups of proteins. However, also the activation of the protein (or any other amino or thiol-group carrier) using the same chemistry is a means to couple covalently to the surface. On the other hand for many applications simple non-covalent absorption to a plasma-etched polymer is sufficient to bind the ligand-layer to the polymer surface adapting know-how from the ELISA-technology.
