document: From the view of analytical science and with the abovementioned considerations, combining a colorimetric biosensing element with a smartphone to assemble an integrated platform will show great promise in modern analytical science (Garg et al., 2015). Therefore, we propose developing a POC biosensing platform, which includes the following three steps: (1) We will design a ready-to-use biosensing cassette with multiple windows that can be used to analyze multiple biomarkers in one patient’s
