Apparatus and methods for analyzing the output of microfluidic devices

摘要

Microfluidic devices for analyzing droplets are disclosed. A described microfluidic device includes a substrate and a microfluidic channel formed on the substrate. The microfluidic channel includes passages where each passage has a mask pattern configured to modulate a signal of a droplet passing through that passage, such that droplets passing through the passages produce signals. The microfluidic device also includes a detector configured to detect the signals. Methods of analyzing droplets with a microfluidic device having a microfluidic channel formed on a substrate are disclosed. A described method includes passing droplets through the passages, modulating signals form the droplets using mask patterns formed on the passages; and detecting the signals.
