Separation of particles based on different sizes, detection of pathogenic bacteria and isolation of leukocytes from whole blood are typical applications of spiral or helical microchannels. Several microfluidic point-of-care (POC) devices have been developed for monitoring HIV/AIDS by counting CD4 cells but researches are still pursuing to develop a more efficient low-cost device that can be used in developing and underdeveloped countries. The present study focuses on developing a CD4+ T-cell counting device for HIV/AIDS monitoring with the aid of a helical microchannel. For the experiment 10 μm sized particles were used for visualization with a fluorescence microscope system. A sample with the viscosity as that of blood and other samples with different viscosities were also prepared to determine the effect of density and viscosity on alignment of the particles. The channels were spun using a DC motor controlled by an Arduino board with a Bluetooth shield. It was found that for low viscosity samples the particles were not aligned when the channel was kept stationary and an alignment was achieved when the channel was spun due to the combination of centrifugal and gravitational forces. For a sample with viscosity as that of blood, alignment of particles were obtained even without spinning. Since an alignment of particles was achieved for a sample with viscosity as that of blood, the same approach can be applied for aligning and counting CD4+ T cells in blood samples collected from patients.
