Abstract: Methods, compositions, and kits for nucleic acid detection.

Abstract: The present invention provides methods and compositions for highly sensitive detection of a metabolite of interest comprising use of a nanodetection device that comprises an anchoring part, a bridging part and a signal producing part wherein the anchoring part is a molecular motor, the signal producing part is a nanorod and the bridging part is a protein that specifically binds to the metabolite of interest.

Abstract: A nanoscale motion detector attaches a gold nanorod (30) to the rotating arm (26) of a molecular structure (10) to cause the nanoparticle to rotate. The molecular structure is an F1-ATPase enzyme. The gold nanorod is exposed to a light source. The long axis of the gold nanorod scatters red light when the nanorod is in a first position. The short axis of the gold nanorod scatters green light when the nanorod is in a second position. A polarizing filter filters the red and green light to detect the rotational motion by observing alternating red and green lights. A detection DNA stand (50) is coupled between the gold nanorod and the molecular structure. The detection DNA strand hybridizes with a target DNA strand (58) if the target DNA strand matches the detection DNA strand to form a structural link between the molecular structure and gold nanorod.

Abstract: An exemplary system and method of employing DNA hybridization for the detection of bio-agents is disclosed as comprising inter alia a biomolecular rotary motor (150); a capture probe DNA fragment (140) effectively attached to said biomolecular motor (150); a target DNA fragment (130) suitably adapted for hybridization with said capture probe DNA (140); a signal probe DNA fragment (120) suitably adapted for hybridization with said target DNA (130); and a fluorescent bead (100) attached to said signal probe DNA (120). Disclosed features and specifications may be variously controlled, adapted or otherwise optionally modified to improve certain device fabrication parameters and/or performance metrics.
