Abstract
Systems and methods for improved measurement of absorbance/transmission through fluidic systems are described. Specifically, in one set of embodiments, optical elements are fabricated on one side of a transparent fluidic device opposite a series of fluidic channels. The optical elements may guide incident light passing through the device such that most of the light is dispersed away from specific areas of the device, such as intervening portions between the fluidic channels. By decreasing the amount of light incident upon these intervening portions, the amount of noise in the detection signal can be decreased when using certain optical detection systems.
Claims37
A fluidic device comprising:
- an article comprising first and second sides;
- a first microfluidic channel segment positioned at the first side of the article;
- first and second adjacent optical elements positioned at the second side of the article, wherein the first microfluidic channel segment is positioned substantially between the first and second optical elements,
- wherein the first optical element is adapted and arranged such that when a portion of the article is exposed to light, the first optical element redirects at least a portion of the light away from a surface portion of the first side of the article, the surface portion being adjacent to the first microfluidic channel segment.
