Abstract:
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.
Abstract:

Abstract:
The disclosure provides a remote control switch of gene interference in living cells by using Oligonucleotides on a Nanoplasmonic Carrier-based Optical Switch (ONCOS) and a near infrared (NIR) laser transmitter. It is possible activate a variety of different nanoscale receivers by tuning optical transmission frequency, which is selectively determined by matching the resonant transmission frequency with the gold nanoplasmonic particle (GNP) carriers.
