MICROFLUIDIC APPARATUS, AND METHOD OF DETECTING SUBSTANCE USING MICROFLUIDIC APPARATUS

摘要

A microfluidic apparatus includes an electrochromic layer (210) including a plurality of individually independently addressable regions (R); a microfluidic layer (270) defining a microfluidic channel (271) for allowing a microfluid (272) to pass therethrough; and a plurality of photodetectors (110) configured to detect light transmit through the microfluid (272). The electrochromic layer (210) is configured to be switched between a first state in which the plurality of individually independently addressable regions (R) of the electrochromic layer (210) are substantially transmissive, and a second state in which at least a first one of the plurality of individually independently addressable regions (R1) of the electrochromic layer (210) in a region (M) corresponding to a position of the microfluid (272) is substantially transmissive, at least a second one of the plurality of individually independently addressable regions (R2) of the electrochromic layer (210) outside the region (M) corresponding to the position of the microfluid (272) is substantially non-transmissive.
