Description
Summary:A new approach to the colorimetric detection of human lung carcinoma cell by enlarging Au-nanoparticles in situ has been reported. The results show that the sensitivity of detecting lung carcinoma cell is ca. 100 cell mL-1. By enlarging Au-nanoparticles immobilized on the nitrocellulose strips in situ with 0.01% HAuCl4 and 0.4 mM NH2OH, detection of lung carcinoma cell by naked eye is available. It will be of great significance in rapid and early clinical diagnosis.
