DNA-mediated dynamic plasmonic nanostructures: assembly, actuation, optical properties, and biological applications

Abstract

Recent advances in DNA technology have made it possible to combine with the plasmonics to fabricate reconfigurable dynamic nanodevices with extraordinary property and function. These DNA-mediated plasmonic nanostructures have been...

Recent Advances in the DNA-Mediated Multi-Mode Analytical Methods for Biological Samples

“…DNA as a double-helix molecule formed by winding two complementary nucleotide chains has the characteristics of structural programmability and high stability [39]. DNAmediated multi-mode probes as the core of DNA-mediated multi-mode analytical methods are usually prepared by integrating various sensing modules with DNA-mediated strategies into one sensing platform.…”

Controlled synthesis of monodisperse gold nanorods with a small diameter of around 10 nm and largest plasmon wavelength of 1200 nm

“…1,3 This unique property in combination with the tunable size, easy surface modification, and good biocompatibility endows AuNRs with promising and fascinating prospects in research applications including catalysis, 4,5 sensing, 6,7 imaging, 8,9 and theranostics. 10,11 The seed-mediated growth method is currently the most widely used method for the synthesis of AuNRs proposed by Murphy et al in 2001 and improved by Elsayed et al in 2003. 12,13 In the method, a gold seed of around 1.5 nm diameter was first prepared, and then the reducing agent ascorbic acid (AA) was used to promote seed growth under an exquisitely designed condition to form AuNRs.…”
