This work addresses the need for real-time 3D tracking of nanoparticles in fluid environments, which is incremental as it applies an existing method to new data.
The authors tackled the problem of tracking gold nanoparticles in three dimensions by developing a digital holographic microscope, achieving observations of 100nm particles in motion in water.
In this paper we present a digital holographic microscope to track gold colloids in three dimensions. We report observations of 100nm gold particles in motion in water. The expected signal and the chosen method of reconstruction are described. We also discuss about how to implement the numerical calculation to reach real-time 3D tracking.
