| PATENT CLAIMS |
Polymerizable complex comprising a nucleic acid molecule which is modified to contain at least one primary amine group & which is derivatized by attachment to an alpha-acryloyl, omega-N-hydroxysuccinimidyl ester of PEG-propionic acid as first polymerizable ethylene-contg monomer unit which, under appropriate conditions, is capable of co-polymn with second polymerizable ethylene-contg monomer unit, said co-polymn producing a polymerized layer to which said nucleic acid mole. is covalently linked
