Hue-based quantitative molecular detection by our SCPT platform. (A) A photograph of our SCPT platform. (B) A photograph of our microfluidic chip. (C) A sequence of optical images obtained by smartphone camera during colorimetric LAMP assay of HPV 16 DNA ranging from 0 to 104 copies per reaction. The images were taken at 0, 20, 30, 40 and 60 min after the start of LAMP incubation. (D) Real-time hue value change (∆Hue) monitoring of LAMP amplification. (E) Threshold time Tt (in minutes), as a function of the HPV 16 DNA concentration (expressed in terms of HPV 16 DNA copies per reaction).
