This paper presents a portable system integrating microfluidic dielectrophoresis (DEP) channel with a CMOS imager for label and lens free detection, and real-time counting of MCF-7 breast cancer cells. The DEP device is designed for trapping the MCF-7 that can simultaneously be imaged using a CMOS sensor. An android application is employed in order to record raw CMOS images. Cells are detected and counted using inbuilt image processing operations of the same application. Average counting accuracy of the system is reported as 90%. Additionally, the whole system is powered with the cell phone battery eliminating the need for an external power supply.
