Abstract
A micro-reactor is provided for observing small particles, cells, bacteria, viruses or protein molecules in a fluid. The micro-reactor includes a first channel for containing the fluid and a second channel adjacent to the first channel. A gap connects the first channel and the second channel and a window transparent to the method of inspection is provided at the gap. A static or dynamic gradient, such as a gradient in concentration of a chemical or biological material, in pressure, in temperature, in electric potential, or in magnetic field, is applied across the gap, thereby causing the particles to cross the gap. By detecting a property of the particles upstream in the first channel and then applying a pressure burst over the channels when the property meets certain pre-set criteria, only selected particles can be placed in the gap.
