Assembly of Ag@Au Nanoparticles Using Complementary Stranded DNA Molecules and Their Detection Using UV-Vis and Raman Spectroscopic Techniques

Autor: Shinya Maenosono, Derrick Mott, Yoshiya Aoki, Nguyen T. B. Thuy

Publikováno v: Scopus-Elsevier

Silver nanoparticles coated by a layer of gold (Ag@Au) have received much attention because of their potential application as ultra sensitive probes for the detection of biologically important molecules such as DNA, proteins, amino acids and many oth

Aqueous synthesis and characterization of Ag and Ag-Au nanoparticles: addressing challenges in size, monodispersity and structure

Autor: Yoshiya Aoki, Derrick Mott, Shinya Maenosono, Nguyen T. B. Thuy

Publikováno v: Philosophical transactions. Series A, Mathematical, physical, and engineering sciences. 368(1927)

In this paper, we demonstrate the synthesis of monodispersed silver nanoparticles (NPs) of controlled size (20.5 ± 3.3 nm) in aqueous phase from a silver hydroxide precursor with sodium acrylate as dual reducing–capping agent. We then coat these N

Phylogenetic relationships among vertebrate visual pigments

Autor: Fumio Tokunaga, Tatsuo Iwasa, Yoshiya Aoki, Seiya Kayada, Osamu Hisatomi

Publikováno v: Vision research. 34(23)

Genomic DNA fragments in exon 4 of chicken, goldfish and salmon visual pigments were amplified by polymerase chain reaction, using oligonucleotide mixtures as primers, and hypothetical phylogenetic trees were drawn up from the deduced amino acid sequ

A Study on the Plasmonic Properties of Silver Core Gold Shell Nanoparticles: Optical Assessment of the Particle Structure

Autor: Prerna Singh, J. D. Lee, Shinya Maenosono, Derrick Mott, Yoshiya Aoki, Nguyen T. B. Thuy

Publikováno v: Japanese Journal of Applied Physics. 50:065004

This paper reports a qualitative comparison between the optical properties of a set of silver core, gold shell nanoparticles with varying composition and structure to those calculated using the Mie solution. To achieve this, silver nanoparticles were

Intensification of surface enhanced Raman scattering of thiol-containing molecules using Ag@Au core@shell nanoparticles

Autor: Shinya Maenosono, Prerna Singh, Derrick Mott, Nguyen T. B. Thuy, Yoshiya Aoki

Publikováno v: Journal of Applied Physics. 109(9):094301-094301-7

In this paper, we study the relationship between nanoparticles’ structure/composition and the chemical nature of the molecules to be identified in surface enhanced Raman scattering (SERS) spectroscopy. Three types of nanoparticles (NPs) were synthe
