1. An optical sensor for detecting nucleic acids in a fluid sample comprising:

  • a) a preformed, unitary fiber optic array comprising a plurality of optical fiber strands, said strands being disposed co-axially and joined along their lengths, said fiber optic array having a proximal and distal end, each of said ends being formed by multiple strand faces of said strands, at least one of said array ends presenting a discrete fiber optic array surface for introduction and conveyance of light energy; and

    b) at least a first and a second nucleic acid attached to a first and second portion, respectively, of said distal array end, said first nucleic acid being optically coupled to and in optical communication with a first of said multiple end faces at said distal array end, and said second nucleic acid being optically coupled to and in optical communication with a second of said multiple end faces at said distal array end.
