| 摘 要： | Platinum nanoclusters were deposited along the supercoiled DNA strands after incubation of cis-(trans-1R，2R-diaminocyclohexane)(dl-camphorato)platinum(Ⅱ) (Cdp)， an analogue of the anti-tumor drug-carboplatin， with DNA and K2PtCl4 for 600 min and then through reduction of dimethylaminoborane (DMAB). The decrease of absorption of DNA at 260 nm indicates the coordination of Cdp and DNA. TEM and AFM were employed to characterize the morphologies and structures of platinum nanoclusters.

| Abstract: | Platinum nanoclusters were deposited along the supercoiled DNA strands after incubation of cis-(trans-1R,2R-diaminocyclohexane)(dl-camphorato)platinum(Ⅱ) (Cdp), an analogue of the anti-tumor drug-carboplatin, with DNA and K2PtCl4 for 600 min and then through reduction of dimethylaminoborane (DMAB). The decrease of absorption of DNA at 260 nm indicates the coordination of Cdp and DNA. TEM and AFM were employed to characterize the morphologies and structures of platinum nanoclusters. |
