Abstract

Surface-enhanced Raman scattering (SERS) is an important, highly sensitive technique for chemical and biological analysis, which is critically dependent upon high-performance metallic substrates. Anisotropic gold (Au)-silver (Ag) alloy nanoboxes are attractive SERS substrates because of the greatly enhanced Raman signals from the strong electromagnetic fields on the sharp corners. Yet, the routine approach of Au-Ag alloy nanobox synthesis is still challenging because of the complicated procedures and use of biologically/environmentally unfriendly reagents. To facilitate the usage of Au-Ag alloy nanoboxes for broad SERS applications, we propose a facile green strategy to synthesize Au-Ag alloy nanoboxes with superior single-particle SERS sensitivity. Our novel straightforward strategy involves HAuCl4 and AgNO3 reduction by ascorbic acid, which is achieved in an aqueous one-pot reaction at ambient temperature. Significantly, the surfaces of the prepared Au-Ag alloy nanoboxes are judiciously designed to introduce nanodots, generating numerous "hot spots" for high Raman signal enhancement as indicated by rigorous numerical simulations. By combining scanning electron microscopy and Raman mapping images, we demonstrate the application of Au-Ag alloy nanoboxes for single-particle sensing SERS activity. The as-prepared Au-Ag alloy nanoboxes are expected to facilitate their further applications in quantitative and ultrasensitive SERS detection.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 03 October 2018.
All research outputs
#12,913,076
of 23,103,436 outputs
Outputs from ACS Applied Materials & Interfaces
#6,859
of 17,651 outputs
Outputs of similar age
#155,796
of 335,281 outputs
Outputs of similar age from ACS Applied Materials & Interfaces
#156
of 461 outputs
Altmetric has tracked 23,103,436 research outputs across all sources so far. This one is in the 43rd percentile – i.e., 43% of other outputs scored the same or lower than it.
So far Altmetric has tracked 17,651 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.7. This one has gotten more attention than average, scoring higher than 60% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 335,281 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 52% of its contemporaries.
We're also able to compare this research output to 461 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 65% of its contemporaries.
