Abstract
Embodiments of the invention are directed to a microfluidic device. The device comprises a flow path structure that includes an inlet microchannel and chambers. The flow path structure is configured as an arborescence extending from the inlet microchannel to the chambers. Thus, liquid introduced in said inlet microchannel can potentially enter the chambers via respective flow paths to remain essentially confined in the chambers, in operation. The device further comprises substances in selected ones of the chambers. That is, a subset of the chambers is loaded with substances adapted for interacting with liquid to yield a detectable change in a property of the liquid and/or the substance in each of the chambers of said subset, in operation. The invention is further directed to related devices, and methods of operation and conditioning.
