Analyzing device with biochip

A device for analyzing at least one analyte, comprising:

• a container having a window:
• a biochip comprising:
• an active face including an active surface onto which are distributed and bound a plurality of ligands used for the analysis and a peripheral zone,
• at least one face opposite to the active face, and
• a transverse peripheral strip connecting the active and opposite faces, comprising several sides;
• and
• an attachment means placed on opposite lateral sides of the active face of the biochip that attaches the biochip to the container through the window, the attachment means including means that are flexible at a level of the window and exert a pressure on the transverse peripheral strip of the biochip to facilitate positioning and/or maintaining in position of the biochip, the biochip and the container delimiting a reaction compartment, the attachment means of the biochip connecting the transverse peripheral strip of the biochip excluding any other part of the biochip, to a frame of the window of the container in order to expose the peripheral zone of the active face of the biochip.
