Plasmonic Nanoparticles - an overview | ScienceDirect Topics

In bulk measurements, the LSPR results in distinctive changes in the extinction of a nanoparticle suspension. The extinction is the result of increases in both nanoparticle absorbance and scatter, and the wavelengths at which plasmonic nanoparticles interact with light can be tuned by varying the composition, shape, and size of the particle (Fig. 3).

General and programmable synthesis of hybrid liposome ...

Dec 01, 2016 · Hybrid liposome/metal nanoparticles are promising candidate materials for biomedical applications. However, the poor selectivity and low yield of the desired hybrid during synthesis pose a challenge. We designed a programmable liposome by selective encoding of a reducing agent, which allows self-crystallization of metal nanoparticles within the liposome to produce stable liposome/metal ...

DNA-encoded morphological evolution of bimetallic [email protected] ...

DNA-mediated synthesis of nanoparticles is a powerful method to access exclusive shapes and surface properties. Previous studies employed seeds containing low-energy facets, such as a simple cubic palladium seed, in the synthesis of Pd-Au bimetallic nanoparticles; however, few studies have investigated whether DNA molecules are influential when a seed containing high-energy facets is used.

Encoded particles are one of the most powerful approaches for multiplex high-throughput screening. Surface-enhanced Raman scattering (SERS) based codification can, in principle, avoid many of the intrinsic limitations due to conventional alternatives, as it decreases the reading time and particle size while allowing for almost unlimited codification.
