“…[ 4 ] In particular, great synthetic control over noble metal nanoparticles has enabled the design of materials with resonances that span from the UV (Ag nanospheres) [ 5 ] to the IR (Au nanoshells). [ 6 ] Non-noble metal materials have the potential to further expand plasmonic functionality and tunability.…”

The field of plasmonics has grown to impact a diverse set of scientific disciplines ranging from quantum optics and photovoltaics to metamaterials and medicine. Plasmonics research has traditionally focused on noble metals; however, any material with a sufficiently high carrier density can support surface plasmon modes. Recently, researchers have made great gains in the synthetic (both intrinsic and extrinsic) control over the morphology and doping of nanoscale oxides, pnictides, sulfides, and selenides. These synthetic advances have, collectively, blossomed into a new, emerging class of plasmonic metal chalcogenides that complement traditional metallic materials. Chalcogenide and oxide nanostructures expand plasmonic properties into new spectral domains and also provide a rich suite of chemical controls available to manipulate plasmons, such as particle doping, shape, and composition. New opportunities in plasmonic chalcogenide nanomaterials are highlighted in this article, showing how they may be used to fundamentally tune the interaction and localization of electromagnetic fields on semiconductor surfaces in a way that enables new horizons in basic research and energy-relevant applications.

“…With plasmonic nanosensors, the colour of the nanoparticle solution can be tuned by changing the composition and morphology of the nanomaterials. [41][42][43] Semiconducting nanoparticles show size-dependent emission properties that cover the whole visible spectrum. 44,45 Nanomaterials have been a true game changer in the field of solution-based sensing due to their easy functionalization, chemical reactivity and outstanding physical properties.…”

With this approach, nonexperts can perform analyses on-site and without utilising electronic readers. This is advantageous in point-of-care diagnostics, in-field measurements and analyses performed in resource-constrained settings. Here we review the main strategies adopted for detecting analytes with the naked eye and at the point of need using plasmonic nanosensors, catalytic nanoparticles and fluorescent nanomaterials. Examples of the detection of ions, glucose, small molecules, peptides and proteins with the nanosensors are explained in detail. IntroductionThe design of sensors for in-field measurements has been a central issue of analytical chemistry for decades. From the diagnosis of diseases at the point of care 1 to the detection of hazardous levels of pollutants 2,3 and the identification of pathogens in food samples, 4,5 there is a growing need for obtaining accurate information about the composition of a sample rapidly and at the point of need. For many years electrochemical sensors have dominated the area of in-field sensing due to the possibility of fabricating all the elements of the sensor with well-known microfabrication techniques. 6,7 These fabrication methods generate portable, compact devices in which the transducers are directly integrated with the circuitry. 8,9 However, although microchips containing electrochemical transducers can be mass-produced, the manufacturing cost of these devices is still too high for certain applications in which the sensor cannot be reutilised or recycled. Electrical readers are also expensive, and therefore their utilisation can only be justified in routine tests, for example in diagnostic tests r...

“…Even though a mirror-like deposition via a silver dicyano ion complex or other additives has been achieved, the complexity and difficulty of achieving completely transparent state hinders its development and further application. Hence, it is necessary to develop Ag-based electrochromic devices with reversible multi-state using a simple and controllable method [13][14][15]. Araki et al [13] deposited Ag onto an indium tin oxide (ITO) nanoparticle-modified ITO electrode via spin-coating and obtained reversible black/mirror state.…”

“…Araki et al [13] deposited Ag onto an indium tin oxide (ITO) nanoparticle-modified ITO electrode via spin-coating and obtained reversible black/mirror state. Araki and his co-workers [14] achieved multi-color states for electrochromic device by controlling the growth of Ag grains under different voltages. In a previous study, our group fabricated an electrodeposition-based Ag/Cu electrochromic device with a reversible three-state optical transformation by using conducting FTO electrode spin-coated with TiO 2 nanoparticles [15].…”

A layer of TiO 2 nanoparticles with size of 100 nm was deposited onto a fluorine-doped tin oxide (FTO) conducting electrode via dip-coating technique, followed by sintering treatment. Multi-state electrodeposition-based electrochromic device was subsequently fabricated by sandwiching gel electrolyte between a modified FTO electrode and a flat FTO electrode. When applied with a suitable voltage, the fabricated device changed its optical state from transparent to mirror or black depending on whether the silver nanoparticles were deposited on the unmodified or the modified FTO electrode. The silver was reversely dissolved into gel electrolyte once the applied voltage was removed. The fabricated device exhibited transmittance below 1% in the black state and reflectance over 70% in the mirror state. Moreover, the transmittance increased to 11% after 2000 cycles, indicative of good device stability.
