Реферат: The present disclosure provides fluidic devices. A fluidic device includes a) a first bondable polymeric layer having a first major surface that is substantially planar; b) a second polymeric layer having a first major surface that is substantially planar; and c) a hydrophilic mask material disposed on a first portion of the first major surface of the first bondable polymeric layer. A surface of the hydrophilic mask material exhibits an advancing contact angle with water of less than 90 degrees. A second portion of the first major surface of the first bondable polymeric layer is bonded to a first portion of the first major surface of the second polymeric layer. The hydrophilic mask material and a second portion of the first major surface of the second polymeric layer are in direct contact with each other at at least one point. An open volume is defined by interstitial space located between the hydrophilic mask material and the second portion of the first major surface of the second polymeric layer. The open volume comprises two or more openings and at least one of the openings is located at an edge of the first bondable polymeric layer. The fluidic devices can be formed to have small volumes for use as precision fluidic devices, such as blood glucose testing strips.
