Description

Flow cytometry is a method by which microparticles and cells in a stream of fluid can be measured. Most currently available cytometers are very large and expensive because they require equipment such as lasers and optics. Our goal was to create a basic lightweight, inexpensive cytometer. The sensor works by passing the fluid with the particles through a specially designed microchannel that forces the particles to flow through in single file. The particles are measured by taking into account their optical properties; an LED of a specific frequency is shined on the particles which excites them, causing them to emit light of another specific frequency. This light can then be measured to detect the particles. Currently, the system is built and operational but suffers from excessive electrical noise. To mitigate the noise, we have used shielding to eliminate as much external interference as possible. In addition, we implemented data filtering in LabView to further reduce noise. Although these measures have drastic...
