英文摘要	The strongly induced circular dichroism (ICD) signals of DNA wrapped around single-walled carbon nanotubes I are shown by the Synchrotron Radiation Facility. In solution, trace amounts of Hg ions have a strong affinity to bind the nucleic bases of DNA-SWCNTs via a pseudo-first-order kinetic reaction. The Hg binding to the bases of DNA results in partial DNA disassociation from the SWCNTs. Such disassociation of DNA from the SWCNTs will decrease the coupling effects of the transition dipole moments between DNA and SWCNTs, thus inducing the ICD signal of DNA-SWCNTs to decrease significantly. Herein, the ICD of DNA-SWCNTs is applied to detect the concentration of Hg ions at.
