Abstract:
1. A process for producing a platinum particle nucleic acid composite comprising platinum particles, the process comprising: providing a nucleic acid specific platinum complex selected from the group consisting of dichloro (2,2′:6′,2″-terpyridine)platinum (II), cis-diaminodichloroplatinum (II), and combinations thereof; reacting said nucleic acid specific platinum complex with a nucleic acid to produce a platinum complex-nucleic acid conjugate; removing any non-conjugated platinum complexes and/or non-conjugated by-products; and reacting the platinum complex-nucleic acid conjugate with a reducing agent to produce the platinum particle nucleic acid composite, wherein the platinum complex-nucleic acid conjugate is formed by the specific reacting of the nucleic acid specific platinum complex with bases of the nucleic acid, wherein the platinum particle nucleic acid composite is catalytically active towards electroless metallization, wherein the platinum particles in the platinum nucleic acid composite cannot be visualized by atomic force microscopy, and wherein the platinum particles in the platinum particle nucleic acid composite are subnanometer in size.
