Growth of PbS nanoclusters on specific sites of programmed oligodeoxynucleotides |
Fig. 6. a PAGE image of the ODN#cod#x2013;PbS complexes. Lane 1 is for type I ODN and lane 2 for type II ODN. The white arrow marks the ODN with 1 QD, the black arrow marks the ODN with a pair of QDs, and the grey arrow marks the naked ODN. b Structure models of the ODN#cod#x2013;PbS complexes. c and d TEM images of the QDs on type I and type II ODN, respectively. |
