Abstract
An example microfluidic device includes an optically transparent first layer having an index of refraction. The microfluidic device also includes an optically scattering second layer spaced from the optically transparent first layer to receive a first fluid and a second fluid between the optically transparent first layer and the optically scattering second layer. The index of refraction is selected to cause total internal reflection where the first layer interfaces with the first fluid and to cause refraction where the first layer interfaces with the second fluid.IPC Classes ?
