Special Issue Information

Dear Colleagues,

Sensing devices use nanotechnology as an ultrasensitive and highly specific analytical tool that can exploit signal readouts in a variety of physical and chemical applications. For example, the SERS effect primarily relies on the excitation of localized surface plasmon resonances at the surface of nanostructured plasmonic materials. Thus, developments in the precise design and fabrication of plasmonic substrates with tailored morphologies, high and reproducible enhancing performances, and (when applicable) multifunctional features have been major driving forces in boosting the technological advances and applications of sensing research. Successfully translating the analytical potential of sensing applications into viable commercial devices is also dependent on the ability to produce excellent plasmonic substrates on a large scale and in a cost-effective fashion.

This Special Issue focuses on presenting and discussing the most recent technological advances in the design of plasmonic nanomaterials in order for them to be applied in diverse fields such as sensing, detection, environmental monitoring, and catalysis.

We kindly invite all experts in the field to submit their manuscripts to be considered for publication. Original research papers, both experimental and theoretical, as well as review articles, are welcome.

Fe and Pd thin film samples have been fabricated in a rapid fashion utilizing the versatile technique of dynamic hydrogen bubble template (DHBT) method via potentiostatic electrodeposition over a copper substrate. The morphology of the samples is dendritic, with the composition being directly proportional to the deposition time. All the samples have been tested as SERS substrates for the detection of Rhodamine 6G (R6G) dye. The samples perform very well, with the best performance shown by the Pd samples. The lowest detectable R6G concentration was found to be 10−6 M (479 μgL−1) by one of the Pd samples with the deposition time of 180 s. The highest enhancement of signals noticed in this sample can be attributed to its morphology, which is more nanostructured compared to other samples, which is extremely conducive to the phenomenon of localized surface plasmon resonance (LSPR). Overall, these samples are cheaper, easy to prepare with a rapid fabrication method, and show appreciable SERS performance. Full article
