Abstract:
Uniform-sized magnetic microparticles are a reliable and gentle way of isolating biological cells from a sample and have been widely used in laboratories for decades. Microfluidics is the manipulation and control of fluids at the sub-millimetre scale. By combining microfluidics and electronics, the small-scale integration and automation of various laboratory processes onto a single chip or device, known as lab-on-a-chip, can be made possible. The detection of magnetic microparticles, which can act as a label for identifying a cell, can provide a means for quantifying various cells in a sample or act as a trigger for other on-chip processes. This presentation focuses on a magnetic sensor that detects single magnetic microparticles as they flow inside a 25 µm deep channel. Although various magnetic sensors have been developed, this approach does not require a permanent magnet, which might interfere with other on-chip circuitry, and has a very simple microfabrication recipe.
