| 中文摘要 | a sensitive and selective colorimetric detection method for mercury(ii) has been well-estabilished in this paper. it was based on the conformation change of mercury-specific oligonucleotides (mso) from random coil structure to hairpin structure upon the addition of hg2+ and the phenomenon of salt-induced unmodified silver nanoparticles (agnps) aggregation. the calibration curve showed that the net absorption ratio value at 395 and 570 nm increased linearly over the hg2+ concentration range of 25-500 nm with a limit of detection of 17 nm. the other environmentally relevant metal ions did not interfere with the determination of hg2+. |
