Highly sensitive smartphone-based detection of Listeria monocytogenes using SYTO9
文献摘要:
Listeriosis is caused by Listeria monocytogenes(LM)and is currently considered to be one of the leading food-borne diseases worldwide,with mortality rate of 20%~30%.Currently,detection methods for LM are time-consuming with low sensitivity,and delayed detection results.SYTO9 has a high affinity for DNA and exhibits enhanced fluorescence upon binding.Therefore,this study used SYTO9 staining and image processing to develop a rapid loop mediated isothermal amplification(LAMP)detection method for LM.Smartphone was successfully used for detecting the color change in different concentrations of LM.Besides,the optimized LAMP reaction temperature was 63℃by color identification,and the limit of detection for LM was 6 copies/μL in the green channel.So,the developed method,based on image processing,is simple,sensitive and rapid,which provides a new idea and method for rapid detection of LM and other food-borne bacterial pathogens.
