摘要：
The invention relates to a micro-device for non-invasive and selective separation and extraction of particles in polydispersed suspensions by means of the strategic use of ultrasounds, laminar flow and standing wave effects in a channel produced in a chip by means of microtechnology. Said device is a resonant multi-layer system comprising a modified "lambda quarter wavelength" treatment channel, which enables the particles to be channelled and separated in a flow inside the substrate channel without touching the walls of the device, in order to avoid problems of adherence. Said micro-device can be used in the field of biomedicine and/or biotechnology for the separation and concentration of cells, preferably human cells, that can be used for investigative and medical methods for diagnosis and treatment.
