Accuparan is a nano and optical technology startup that measures colloidal particles and determines the properties of colloids, emulsions, and suspensions. At Accuparan, we have developed a novel DLS instrument that uses dynamic light scattering techniques to measure particle sizes in nanoscale solutions. It can measure particle size distributions from less than one nanometer to several microns. Also, in Accuparan,  machine learning algorithms have been used to solve the problem of particle imaging of very dilute samples and to reduce the signal-to-noise ratio due to high exposure.
