Abstract
In one example, testing cells extend along a length of a slot. Each testing cell includes a microfluidic channel extending from the slot, a pump to move fluid from the slot into the channel, a discharge nozzle through which fluid exits the channel, a fluid discharger to discharge fluid from the channel through the nozzle and a photosensor. A light guide is provided to receive light from an external light source and is to serially transmit the light to the microfluidic channel of each of the plurality of testing cells.
