General Defocusing Particle Tracking (GDPT)
Welcome to the site for the General Defocusing Particle Tracking (GDPT) method, a 3D particle tracking method specially suited for microfluidics that requires only standard laboratory equipment: microscope, light source, and camera.
For more information about the working principles of the method, please refer to:
