    Why Lab on chip Thanks to miniaturisation down to micron & nano level:

    small dimensions function integration possible (dsp, rf-wireless)(mm, m, nm) efficient thermal and material transport

    cheap, easy for mass productionportable, point of analysisdisposable

    small sample volume fast response(L, nL, pL) high throughput

    multi parallel analysis, matrix arraysingle cell/molecule detectionless chemical waste

    high sensor-sample ratio high sensitivityhigh signal to noise

    Shrink volume by 108Improve power efficiency by108
