“…Owing to the tunable LSPR, plasmonic nanoplatelets are widely used in sensing, imaging, and catalysis. − Plasmonic nanoplatelets, if they are Janus and are positioned at the interface between two materials, can potentially enable interfacial catalysis and sensing of molecules transporting across the interfaces . Compared to Janus nanospheres − and 2D graphene, graphene oxide, and TMDs, − the preparation of Janus plasmonic metal nanoplatelets is extremely challenging because the high-aspect-ratio nanoplatelets are susceptible to chemical etching and thermally induced shape evolution at elevated temperatures …”

The preparation of Janus plasmonic metal nanoparticles has remained challenging because of their susceptibility to chemical etching and incompatibility with high-temperature processing. Instead of the conventional methods of using Pickering emulsion and vapor deposition, herein Janus silver nanoplatelets (J-AgNPs) with two chemically distinct surfaces are fabricated via a disparate electrostatic adsorption approach. The approach avoids corrosive chemicals and elevated temperatures that degrade the AgNPs. The J-AgNPs show great potential in stabilizing emulsions and forming layered nanostructures at the interfaces. This novel method enables the design of plasmonic nanomaterials at the liquid−liquid and solid−liquid interfaces for colloidal stabilization.

“…Recently, Janus materials have attracted tremendous attention in various applications such as functional surfactants, photoelectric materials and catalytic agents due to its two distinct faces with anisotropic properties [14][15][16]. Among these Janus-type materials, the twodimensional (2D) ones with asymmetrical properties on each side are called Janus film [16].…”

AuNPs monolayer doping Poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT : PSS) film on interdigitated electrode had been fabricated into AuNPs/PEDOT : PSS Janus film sensor to detect hydrogen sulfide (H 2 S). The results show that the Janus film sensors have a wide measurement range of H 2 S concentration. The sensitivity of PEDOT : PSS/AuNPs sensor grows up with the thickness of Janus film increases. The resistance response of AuNPs Janus film was affected little by the rough surface states of PEDOT : PSS film. In addition, the PEDOT : PSS/AuNPs film sensor had been used again to detect H 2 S. This work presents a platform to inspire a novel high sensitive chemiresistive sensor via nanoparticles monolayer.

“…Janus composite nanoparticles have drawn significant interest because of their potential applications in drug delivery, catalysts, detection, electronic devices, and other areas in recent years . To prepare a Janus composite nanostructure, many synthetic methods have been applied successfully, such as Pickering emulsion polymerization, the single‐crystal template method, and surface‐initiated free‐radical polymerization . Among these, the self‐assembly method is of considerable interest because of its simplicity and facility to control .…”

“…Similarly, polymeric components are also important factors for the performance of Janus composite nanoparticles. To date, many kinds of polymers have been used to prepared Janus nanoparticles; these include polystyrene, poly(ethylene glycol), poly( N ‐ispropyl acrylamide), and poly(acrylic acid) . Polythiophene and its derivatives are one kind of important semiconducting polymers with good optoelectronic properties, low cost, and good processability .…”

A series of Janus composite poly(3-hexyl thiophene)-b-poly(3-thiophenehexanethiol)-gold nanoparticles were synthesized by self-assembly at the water-oil interface, and their photoelectric performance was investigated. The results show that the precise Janus composite nanostructure could be controlled by the adjustment of the reaction temperature and stirring time. The UV-visible measurement revealed that the absorption maximum had an appreciable redshift, and the photoluminescence (PL) spectra indicated that the PL intensity of poly(3-hexyl thiophene)-b-poly[3-(6-thiolhexyl thiophene)] decreased upon the addition of gold nanoparticles. In addition, compared to a common composite of poly(3-hexyl thiophene), the conductivity properties of the Janus composite nanostructure increased remarkably. Therefore, the Janus composite nanoparticles have the potential for applications in photovoltaic devices.
