Researchers employed a lensless imaging method to rapidly count CD4 T cells using CMOS (complementary metal-oxide semiconductor) sensor – the same imaging sensor found in cell phone cameras. The captured CD4 T cells were counted rapidly and automatically from unprocessed whole blood, creating a portable, battery-operated, inexpensive, and microscope-free CD4 T cell counting platform with a long shelf-life.
