From lab-scale to lab-on-card: Loop-mediated isothermal amplification of biological samples

Abstract

This work aims to translate lab-scale techniques for the detection of diseases towards lab-on-card(LOC) devices. Indeed, these point-of-care(POC) tests allow detecting diseases in resource-limited areas. The necessary functions of the LOC can be split up into four different sections: extraction of the cells from the biological sample, lysis of the cells to harvest DNA, DNA amplification based on loop-mediated isothermal amplification(LAMP) and DNA detection by adding SYBR Green I nucleic acid stain. These functionalities have separately been tested on LOCs. The results of the individual functions show that a fully functional POC device is an achievable goal.
