摘要

以肼为主还原剂，壳聚糖为次还原剂、生长引导剂和稳定剂，一锅法制备了稳定的水分散多支各向异性金纳米颗粒。由于存在横向和纵向重叠的局部表面等离子体共振(LSPR)吸收，它们在紫色到蓝色范围内是可调的。纵向LSPR吸光度在近红外范围内。这为生产各向异性金纳米粒子提供了一种简单的替代方法。

Colour tuneable anisotropic, water-dispersible gold nanoparticles stabilized by chitosan

We present a novel one-pot synthesis of stable water dispersible multi-branched anisotropic gold nanoparticles using hydrazine as the principal reducing agent and chitosan as the secondary reducing agent, growth directing agent and stabilizer. They are colour tuneable in the purple to blue range due to the presence of both transverse and longitudinal overlapping localized surface plasmon resonance (LSPR) absorptions arising from the multi-branched nanoparticle morphology. The longitudinal LSPR absorbance tails into the near IR range. This provides a simple alternative approach to producing anisotropic gold nanoparticles.

期刊介绍： Gold Bulletin is the premier international peer reviewed journal on the latest science, technology and applications of gold. It includes papers on the latest research advances, state-of-the-art reviews, conference reports, book reviews and highlights of patents and scientific literature. Gold Bulletin does not publish manuscripts covering the snthesis of Gold nanoparticles in the presence of plant extracts or other nature-derived extracts. Gold Bulletin has been published over 40 years as a multidisciplinary journal read by chemists, physicists, engineers, metallurgists, materials scientists, biotechnologists, surface scientists, and nanotechnologists amongst others, both within industry and academia. Gold Bulletin is published in Association with the World Gold Council.
