document: Current nanotechnology provides the following advantages. First, biosensors can integrate each conventional technique into a platform that is convenient to be set as the base of POC. Second, biosensors recognise biomarkers and generate data rapidly, sensitively, specifically, and reliably. Compared with conventional methods, they are simpler, friendlier, and more cost-effective to use. Third, biosensors not only minimise the number of samples for analysis but also demonstrate portability,
