DEVICE, SYSTEM AND METHOD RELATIVE TO THE PRECONCENTRATION OF ANALYTES

The invention proposes several aspects of a Micro-Nano-Micro (MNM) device. According to one aspect, a plurality of observation channels are positioned in parallel, and each has a smaller cross-section in order to generate a disturbance in order to cause preconcentration. The cross-sections of two se...

Zusammenfassung:	The invention proposes several aspects of a Micro-Nano-Micro (MNM) device. According to one aspect, a plurality of observation channels are positioned in parallel, and each has a smaller cross-section in order to generate a disturbance in order to cause preconcentration. The cross-sections of two separate channels are different. According to another aspect, the observation channel has a smaller width, preferably with a constant depth. According to another aspect, a method for analysing and/or distinguishing between and/or sorting analytes is presented. Several types of analytes can be used. According to one aspect, a method for manufacturing a device according to the invention is presented.
