Development of Organic Phosphorus Fluorescence Test Stripfor Traditional Chinese Medicine
Abstract:Objective:To make it suitable for on-site rapid screening and identification of organic phosphorus in traditional Chinese medicine.Methods:CdTe@SiO2 Fluorescent nanoparticles were covalently conjugated with monoclonal antibodies against organic phosphorus and were employed in the development of lateral flow strip assay by using the immunofluorescence technique.Results:This rapid test strip,specially for parathion,coumaphos and fensulfothion,has a detection limit as low as 10~30 ng·g-1.It is easy of use and only takes 15~20 min to finish the test.Conclusion:Organophosphorus fluorescent strip is wide in scope,simple in operation,high in sensitivity and specificity,and can be widely used in Chinese medicine field screening and detection of organophosphorus residue,has important economic value and social significance.
