Synthesis and Characterisation of Hybrid Gold/Polymer Nanoparticles for Bioassay Application SUBMITTED BY TARA LOUISE SCHILLER MASTERS APPLIED SCIENCE PRESENTED TO THE SCHOOL OF PHYSICAL AND CHEMICAL SCIENCES IN PARTIAL FULFILMENT OF THE REQUIREMENTS OF THE DEGREE OF DOCTOR OF PHILOSOPHY January 2010
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).[PDF]Get Price
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-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.Get Price
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.
Mar 27, 2018 · Seeds enclosed by high-energy facets act as facile nucleation sites in nanoparticle growth and could suppress the effect of DNA. We report the DNA-encoded control of the morphological evolution of bimetallic [email protected] core-shell nanoparticles from a concave palladium nanocube seed containing high-indexed facets.
With a smaller ion radius compared to Y3+, when Lu3+ partially replace Y3+ in the NaYF4 UCNPs during nanoparticle synthesis, nucleation process is suppressed and the growth process is promoted, which are favorable for increasing the nanoparticle size and coating a thicker shell onto the core UCNPs.[PDF]Get Price
