1. An apparatus, comprising:

  • an array of sensors for detecting a chemical reaction at a plurality of reaction sites, each sensor in the array having at least one chemically-sensitive field effect transistor (chemFET), wherein a plurality of the sensors in the array have a horizontal or vertical array pitches of ten micrometers or less; and

    wherein body terminals of a first chemFET and a second chemFET of sensors in the array are connected to a common body bias voltage source line.
