It’s an important molecular marker and can be used to distinguish early gastric cancer and atrophic gastritis. The papers published in PLos One 2012;e47563.

The oligonucleotide concentration that can be detected is 0.2pM, and Antigen concentration is 0.01nM, and the sensitivity and specificity is over ELISA methods. The multicomponent simultaneous detection can be realized because of different colors depended on the quantum dot size. The paper published in Analytical Chemistry (2008;80:7996-8001). Nature Nanotechnology listed it as Research Highlight and commented it on column of Top Down and Bottom Up in the 2008 period. It says “carbon nanotubes combined quantum dots can be highly sensitive to detect DNA and Antigen” “this system can be extended to biosensor applications”. He firstly reported the phenomena that quantum dots modified by mercaptoacetic acid can enhance the specificity of PCR and the principles of quantitative PCR method based on quantum dot fluorescence quenching, and applied the patents(ZL200610026091.1), which is more significant for testing of micro nucleic acid. He firstly reported the pollution-free and controlled synthesis of nano silver based bacteria as the template which is linked with Raman molecular whose detection signals can be increase 1011 times. The paper is published in Green Chemistry (2010;12:2038-2042). In order to detect out minor amount of maker in saliva, he conduct a method to detect out the microscale antibody in saliva by magnetic Nano particle mission clusters which combines fluorescent quenching fight gene probe and double features protein that can combine Fc fragments of antibody and has the features of MboI enzyme cutting. The method’s sensitivity can reached 0.1ng/mL which is significant to the detection of early and few maker of AIDS HIV, hepatitis virus, and tumor. The paper is published in Analyst (2011; 136:679-683). He established the principles of quantitative PCR technology based on the fluorescence quenching of quantum dots and achieve the invention patents (ZL200610026091.1) which transferred to the Shanghai bio-pharmaceutical company and developed a series of kits.
