4 - Fluorescence measurements, imaging and counting by a smartphone

Abstract

With the development of science and technology, smartphone has become a necessary communication tool for everyone. It not only has the corresponding communication function but also can be used for data recording and processing. Thus, it is of great advantage to develop a smartphone-based sensor. This chapter is focused on the introduction of three common detection strategies by using a smartphone as a portable sensing device: spectral detection, imaging image analysis and particle counting analysis. Finally, a conclusion and prospects are provided to extend the application of smartphone-based devices.
