Abstract
The present disclosure is drawn to microfluidic devices. The microfluidic device includes a microfluidic well, a layered composite stack, and an optical sensor. The layered composite stack includes an optical filter composited with an etch-stopping layer. The optical filter defines the microfluidic well. The optical sensor is associated with the microfluidic well and has the optical filter positioned therebetween.
Claims8
A microfluidic device, comprising:
- a microfluidic well;
- a layered composite stack including an optical filter composited with an etch-stopping layer, wherein the microfluidic well is formed by the optical filter, and
- an optical sensor optically associated with the microfluidic well and having the optical filter positioned therebetween:
- wherein the etch-stopping layer is optically transparent, is positioned between the optical sensor and the optical filter, and forms the microfluidic well with the optical filter.
