CONCURRENT MONITORING OF A PLURALITY OF SAMPLES BY AN ARRAY OF BIOSENSING ELEMENTS

摘要

A system and method are presented for monitoring detectable responses from multiple biosensing elements while in contact with multiple samples located in an array. The system (1000) comprises an exciting unit (100), and a detection unit (120). The exciting unit (100) is configured for producing an array of exciting signals (102) each characterized by a frequency differing from those of the other exciting signals, and exciting a corresponding array of the biosensing elements (110), thereby enabling each biosensing element to generate a response signal (130) tagged by the different frequency. The detection unit (120) comprises a single receiving element associated with said array of biosensing elements (110) and configured for concurrently receiving the multiple response signals and generating a single output signal (140) indicative thereof. The system thereby enables to identify signal parts corresponding to the response signals of the spatially separated biosensing elements.
