    摘要: The disclosure relates to metallic nanophotonic crescent structures, or “nanocrescent SERS probes,” that enhance detectable signals to facilitate molecular detections. More particularly, the nanocrescent SERS probes of the disclosure possess specialized geometries, including an edge surrounding the opening that is capable of enhancing local electromagnetic fields. Nanosystems utilizing such structures are particularly useful in the medical field for detecting rare molecular targets, biomolecular cellular imaging, and in molecular medicine.

    摘要: This invention pertains to the in vitro detection of proteases using a single peptide-conjugate nanocrescent surface enhanced Raman scattering (SERS) probes with at least nanomolar sensitivity. The probe enables detection of proteolytic activity in extremely small volume and at low concentration. In certain embodiments the probes comprise an indicator for the detection of an active protease, where the indicator comprises a nanocrescent attached to a peptide, where said peptide comprises a recognition site for the protease and a Raman tag attached to the peptide.

    摘要: This invention provides a nanoplasmonic molecular ruler, which can perform label-free and real-time monitoring of nucleic acid (e.g., DNA) length changes and perform nucleic acid footprinting. In various embodiments the ruler comprises a nucleic acid attached to a nanoparticle, such that changes in the nucleic acid length are detectable using surface plasmon resonance. The nanoplasmonic ruler provides a fast and convenient platform for mapping nucleic acid-protein interactions, for nuclease activity monitoring, and for other footprinting related methods.
