Abstract:
1. A particle sorting system comprising: an inlet duct for conveying therethrough a liquid containing particles having a predetermined characteristic and particles not having a predetermined characteristic wherein a) the inlet duct branches into a microstructured system of a plurality of main channels which are operated in parallel and simultaneously fed with the liquid, each having a sorting module, two outlet channels and a switching region for separating particles having the predetermined characteristic into a first receiving channel from particles that do not have the predetermined characteristic, which flow into a second receiving channel; and b) each sorting module comprising at least one first sensor which detects and classifies the particles having the predetermined characteristic arranged on each main channel inside a sorting module, a second sensor which measures the velocity of the particles having the predetermined characteristic and a sorting actuator controlled by each said sensor arranged on each said switch unit, each said sorting actuator distributing particles having the predetermined characteristic to one of said two outlet channels and particles not having the predetermined characteristic to the other of said two outlet channels.
