SpletAbstract Polydimethylsiloxane (PDMS) is commonly used in medical devices because it is non-toxic and stable against oxidative stress. Relatively high blood platelet adhesion and the need for chemical crosslinking through curing, however, limit its utility. SpletPDMS was initially bonded to itself (Duffy et al., 1998a) by plasma oxidation of its surfaces. The methyl groups existing on the surface of the PDMS make it inert and hydrophobic. Plasma oxidation opens hydroxyl radicals (hydrophilic) on the surface of the PDMS.
