Claim Text:
1. A micro-channel chip, integrated as a single layer or multi-layer, comprising two gas control channels (GC a liquid inlet channel, disposed perpendicularly without intersecting to GC a liquid outlet channel, disposed perpendicularly without intersecting to GC JC a piston channel, integrated with Valve the piston channel being much longer than each of valve channels of Valve a micro pump, controlled by an ordered loop of digital commands of a 1-by-2 matrix, beginning with (1, 1), followed by (0,1), then by (1,0) and back to (1,1), corresponding respectively to a gas pressure of GC the micro pump, made of any materials, which includes the two micro-valves Valve a plurality of micro-channels, joining each other at a plurality of joints (M's), which are holes of a size substantially smaller than that of the micro-channels as passages for the liquid unless otherwise closing off under the a high pressure difference; one of said gas control channels (GC communicating with one end of said piston channel and communicating with said two micro-valves and said liquid inlet channel respectively via said micro-channels, the other one of said gas control channels (GC communicating with said two micro-valves and said liquid outlet channel respectively via said micro-channels, the other end of said piston channel communicating with one of said micro-valves via said micro-channels, wherein I) when a liquid inputs to the input channel: both GC II) GC III) when the piston channel is filled with the liquid: GC GC making the liquid to flow from the piston channel to the outlet channel, not to the inlet channel; and IV) when the outlet channel is filled with the liquid from the piston channel: GC
