 here 
 we report the preparation of poly(oligonucleotide ) brush polymers 
 and amphiphilic brush copolymers from nucleic acid monomers via graft - through 
 polymerization . 
 we describe the polymerization of pna - norbornyl monomers 
 to yield poly - pna ( poly(peptide nucleic acid ) ) via ring - opening metathesis polymerization ( romp ) with the initiator , ( imesh2)(c5h5n)2(cl)2ruchph.1 in addition , we present the preparation 
 of poly - pna nanoparticles from amphiphilic block copolymers and describe 
 their hybridization to a complementary single - stranded dna ( ssdna ) 
 oligonucleotide .
