    Abstract: Methods and apparatuses relating to large scale FET arrays for analyte detection and measurement are provided. ChemFET (e.g., ISFET) arrays may be fabricated using conventional CMOS processing techniques based on improved FET pixel and array designs that increase measurement sensitivity and accuracy, and at the same time facilitate significantly small pixel sizes and dense arrays. Improved array control techniques provide for rapid data acquisition from large and dense arrays. Such arrays may be employed to detect a presence and/or concentration changes of various analyte types in a wide variety of chemical and/or biological processes.

    Abstract: Disclosed are nucleic acid probe arrays and methods of identifying and sequencing nucleic acids in a population of nucleic acids using the arrays. The method is preferably performed by annealing a nucleic acid template to an anchor primer attached to a durface of the array. At least one anchor in the array has a sequence complementary to sequences at the 5' and 3' termini of a target nucleic acid.The annealed linear target nucleic acid is circularized using one or two ligation reactions. In one embodiment, one liggation is issued. Annealing of of the linear nucleic acid results in juxtaposition of the 5' and 3' termini of the target nucleic acid on the anchor primer. Addition of a ligase results in circulization of the target nucleic acid. This circularized nucleic acid is a template for extension of the anchor primer in a rolling circle amplification reaction. An extended anchor primer containing multiple copies of a sequence complementary to the circular mucleic acid is also referred to herein as a anchor primer nucleid acid-nucleic acid concatamer. The presence of multiple copies of the complementary sequence facilitates detection of the nucleic acid. Thus, the method provides for a highly sensitive method of detecting a desired nucleic acid attached at a discrete location on the array.
