Brownian motion of latex nanoparticles
Brownian motion of latex nanoparticles of 270 nm diameter in water. Brownian motion of latex nanoparticles D=270 nm, taken on an optical microscope with a 10x objective, illumination by an IR laser.
Magnetic nanoparticles
Magnetic nanoparticles (50-300 nm) used to isolate DNA and RNA. Dispersed in water. Observation using an ultramicroscope. At about the eighth second of the video, a magnetic field directed vertically turns on, the particles begin to line up and move along the magnetic fields.
