Special Issue Information

Dear Colleague,

Gold-based nanosystems constitute one of the most interesting systems in the nanoworld because of the broad spectrum of applications they can find, ranging from analyte detection, nanomedicine and the mimicry of enzymes, just to mention a few examples. The size and shape of the nanoaggregates allow one to tune the properties of the gold core, while the introduction of specific functional groups on the passivating monolayer is portal to modulate the interaction with the surroundings: A target substrate, a protein, and a receptor. In spite of the fact that the literature on the field increases at an exponential rate, I believe that there is space for sound contributions that are able to conjugate the synthesis and applications of these nanosystems on solid experimental bases.

This Special Issue will cover all types of gold nanosystems and their applications. Original research contributions (full papers or communications), as well as reviews, either broad in scope or devoted to specific issues pertinent to gold nanosystems, will be considered. All submissions should be in line with the high-quality standard of the journal Nanometerials and will be subjected to a rigorous peer-review process. New synthetic protocols and new applications of gold nanosystems are particularly welcome. Submission of papers across different disciplines are highly encouraged in line with the interdisciplinary character of the journal.

For this reason, in view of your expertise in the field I am inviting you to contribute a manuscript (communication, full paper or review) to this special issue. As outlined above, the scope is broad and all types of gold nanosystems (from nanoparticles, to nanostars, nanorods, and nanowires) will be welcome, as well as all diverse applications one may envision for them.

I look forward to receiving a positive reply and wish you all the best in your scientific endeavors.

Best regards,

Prof. Paolo M. Scrimin

In this work, a facile, environmentally friendly method was demonstrated for the synthesis of Ag-Au bimetallic nanoparticles (Ag-AuNPs) supported on reduced graphene oxide (RGO) with alginate as reductant and stabilizer. The prepared Ag-AuNPs/RGO was characterized by scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). The results indicated that uniform, spherical Ag-AuNPs was evenly dispersed on graphene surface and the average particle size is about 15 nm. Further, a non-enzymatic sensor was subsequently constructed through the modified electrode with the synthesized Ag-AuNPs/RGO. The sensor showed excellent performance toward H2O2 with a sensitivity of 112.05 μA·cm−2·mM−1, a linear range of 0.1–10 mM, and a low detection limit of 0.57 μM (S/N = 3). Additionally, the sensor displayed high sensitivity, selectivity, and stability for the detection of H2O2. The results demonstrated that Ag-AuNPs/RGO has potential applications as sensing material for quantitative determination of H2O2. Full article

Title: DNA-assisted assembly of gold nanostructures and their specific optical properties
Author: Zhong Chen
Email: chenzhong@mail.sysu.edu.cn
Abstract:
Gold nanocrystals have attracted considerable attentions due to their excellent physical , chemical properties and extensive applications in plasmonics, spectroscopy, biological detection and biomedicine. Generally, gold nanoparticles are able to readily modified and arranged with protein molecules, DNA sequences, as well as viruses. Over the past two decades, DNA as the best candidate are widely utilized for building plenty of discrete nanoarchitectures by virus of its programmability, stability, specifity and adapt to functionalization. This review concentrates on the DNA-based assembly of gold nanostructures and their resultant extraordinary optical properties including plasmonic extinction, surface enhanced fluorescence (SEF), surface-enhanced Raman scattering (SERS) and plasmonic chirality.
