Modular assembly of plasmonic core–satellite structures as highly brilliant SERS-encoded nanoparticles

Herein, we present a fabrication approach that produces homogeneous core–satellite SERS encoded particles with minimal interparticle gaps (<2–3 nm) and maximum particle loading, while positioning the encoding agents at the gaps.

Towards encoded particles for highly multiplexed colorimetric point of care autoantibody detection

Multiplexed, scanner-based colorimetric detection of autoantibodies in plasma was achieved using graphically encoded particles and gold nanoparticles.

Three-Party Simultaneous Quantum Secure Communication with Unidirectional Qubit Transmission

A three-party quantum secure direct communication protocol is proposed, in which the qubit transmission forms a closed loop. In this scheme, each party implements the corresponding unitary operations according to his secret bit value over the quantum channels. Then, by performing Bell measurements on the encoded particles, each party can extract the other two parties’ secret information simultaneously. Thus the three parties realize the direct exchange successfully.
