1. A process for detecting or quantifying more than one nucleic acid of interest in a library comprising the steps of:
- a) providing(i) an array of fixed or immobilized nucleic acids identical in part or whole to sequences of said nucleic acids of interest;
(ii) a library of nucleic acid analytes which may contain the nucleic acids of interest sought to be detected or quantified;
(iii) a first set of primers; and
(iv) polymerizing means for synthesizing nucleic acid copies of said nucleic acid analytes using said first set of primers;
b) contacting said nucleic acid analytes with said first set of primers to form a first bound entity;
c) extending said bound first set of primers by means of template sequences provided by said nucleic acid analytes to form first nucleic acid copies of said analytes;
d) separating said first nucleic acid copies from the said analytes;
e) repeating steps b), c) and d) until a desirable amount of first nucleic acid copies have been synthesized;
f) hybridizing said nucleic nucleic acid copies formed in step e) to said array of nucleic acids provided in step (i); and
g) detecting or quantifying any of said hybridized first nucleic acid copies obtained in step f).

Abstract
This invention provides novel compositions and processes for analyte detection, quantification and amplification. Nucleic acid arrays and libraries of analytes are usefully incorporated into such compositions and processes. Universal detection elements, signaling entities and the like are employed to detect and if necessary or desirable, to quantify analytes. Amplification of target analytes are also provided by the compositions and processes of this invention.
