Abstract:

A micro-fluidic chip comprises a chip base, a hemispherical or curved lens, and a securing portion. The chip base has a flow cell and a micro-fluidic channel defined therein. The micro-fluidic channel is fluidly connected to the flow cell to deliver fluid to and from the flow cell, respectively via a fluid input port and a fluid output port. The lens has an apex and a base. The apex is positioned within the flow cell. The securing portion is affixed to the chip base such that the lens is sandwiched between the chip base and the securing portion. The securing portion has a circular cavity defined therein in a surface adjacent the chip base, for receiving the base of the lens. The securing portion further has separate light input and output channels to allow light in and out, respectively, of the circular cavity and the lens.
