The resistance of a monolayer of complexes of the double-stranded DNA with quantum dots were computed. It was shown that with the non-competitive DNA hybridization and in the presence of monovalent positively charged ligands in the solution, a decrease in resistance occurs as compared to that for uncharged ligands. It is shown that the charged ligands enhance the sensitivity of the DNA chips as compared to the uncharged ones.

插入带电配体存在下DNA-量子点复合物单层的电导率

计算了双链DNA与量子点的复合物单层的电阻。结果表明，与非竞争性DNA杂交相比，溶液中存在一价带正电的配体时，与不带电的配体相比，电阻降低了。结果表明，与不带电荷的配体相比，带电荷的配体增强了DNA芯片的敏感性。
