Abstract

Hg2+ and Ag+ are two environmental pollutants which have serious toxicity and are widely distributed, the Hg2+ and the Ag+ can seriously threaten the environment and human beings even under low concentration, and serious and permanent damage is caused. The standard of drinking water is strictly limited by the World Health Organization. Therefore, establishment of an efficient and sensitive analysis method capable of simultaneously detecting Hg2+ and Ag+ is of great importance to the fields of environmental monitoring, food safety and the like. The invention provides a method capable of simultaneously detecting Hg2+ and Ag+. The method adopts a nanocapsule-nucleic acid biomolecule compound based on an exonuclease cyclic amplification technology, the simultaneous detection of Hg2+ and Ag+ can be realized, the detection sensitivity is obviously improved on the premise of ensuring high specificity, and meanwhile, the detection sensitivity is greatly improved; and meanwhile, a wider linear detection range for Hg2+ and Ag+ is further obtained.

Description

technical field

[0001] The present invention relates to Hg 2+ and Ag + Simultaneous detection, specifically related to a simultaneous detection of Hg 2+ and Ag + The nanocapsule-nucleic acid biomolecule compound and its preparation method based on exonuclease cycle amplification technology and biomolecular recognition technology belong to the field of environmental monitoring and nanobiotechnology. Background technique

[0002] Mercury ion (Hg 2+ ) and silver ions (Ag + ) are two metal ions with severe toxicity and are also widely distributed environmental pollutants, which pose serious threats to the environment and human beings even at low concentrations, causing severe and permanent damage. More seriously, through polluted water bodies, Hg 2+ and Ag + It can continuously accumulate in agricultural and aquatic products and enter the human food chain. If prolonged exposure to Hg 2+ and Ag + In a polluted environment, it will lead to the slow occurrence of degenera...
