Abstract
Design and properties of a plasmonic modulator in situ tunable by electric field are presented. Our design comprises the creation of periodic surface pattern on the surface of an elastic polymer supported by a piezo-substrate by excimer laser irradiation and subsequent selective coverage by silver by tilted angle vacuum evaporation. The structure creation was confirmed by AFM and FIB-SEM techniques. An external electric field is used for fine control of the polymer pattern amplitude, which tends to decrease with increasing voltage. As a result, surface plasmon-polariton excitation is quenched, leading to the less pronounced structure of plasmon response. This quenching was checked using UV-Vis spectroscopy and SERS measurements, and confirmed by numerical simulation. All methods prove the proposed functionality of the structures enabling the creation smart plasmonic materials for a very broad range of advanced optical applications.

Abstract
![]()
Biomaterials capable
of precisely controlling the delivery of agrochemicals/biologics/drugs/fragrances
have significant markets in the agriscience/healthcare industries.
Here, we report the development of degradable electroactive polymers
and their application for the controlled delivery of a clinically
relevant drug (the anti-inflammatory dexamethasone phosphate, DMP).
Electroactive copolymers composed of blocks of polycaprolactone (PCL)
and naturally occurring electroactive pyrrole oligomers (e.g., bilirubin,
biliverdin, and hemin) were prepared and solution-processed to produce
films (optionally doped with DMP). A combination of in silico/in vitro/in
vivo studies demonstrated the cytocompatibility of the polymers. The
release of DMP in response to the application of an electrical stimulus
was observed to be enhanced by ca. 10–30% relative to the passive
release from nonstimulated samples in vitro. Such stimuli-responsive
biomaterials have the potential for integration devices capable of
delivering a variety of molecules for technical/medical applications.

Abstract
Plasmon-induced diazonium reduction was used to graft an organic semiconductor, namely oligo(bisthienylbenzene) (BTB), onto square arrays of gold nanoparticles (NPs) of various diameters. Grafting was evidenced by scanning electron microscopy (SEM) measurements by the extinction spectra of the localized surface plasmon resonance, as well as by Raman and energy dispersive X-ray (EDX) spectroscopies. We show that BTB is selectively deposited around the NPs. The thickness of the layer increases with increasing irradiation time and reaches a limit which depends on the size of the NPs with the thicker organic layers being generated for smaller NPs. Under polarized irradiation, BTB growth is strongly anisotropic. Starting from arrays with square gratings and spherical NPs, long-range plasmon-induced anisotropic growth makes it possible to generate in the direction of the polarized light, lines, columns, or lines and columns of NPs connected by an organic semiconductor. These results demonstrate that the growth is due to hot electrons.

Abstract
This paper describes a rapid bottom-up approach to selectively functionalize gold nanoparticles (AuNPs) on an indium tin oxide (ITO) substrate using the plasmon confinement effect. The plasmonic substrates based on a AuNP-free surfactant were fabricated by electrochemical deposition. Using this bottom-up technique, many sub-30 nm spatial gaps between the deposited AuNPs were randomly generated on the ITO substrate, which is difficult to obtain with a top-down approach (i.e., E-beam lithography) due to its fabrication limits. The 4-Aminodiphenyl (ADP) molecules were grafted directly onto the AuNPs through a plasmon-induced reduction of the 4-Aminodiphenyl diazonium salts (ADPD). The ADP organic layer preferentially grew in the narrow gaps between the many adjacent AuNPs to create interconnected AuNPs. This novel strategy opens up an efficient technique for the localized surface modification at the nanoscale over a macroscopic area, which is anticipated to be an advanced nanofabrication technique.

Abstract
Plasmonic nanoconstructs are widely exploited to confine light for applications ranging from quantum emitters to medical imaging and biosensing. However, accessing extreme near-field confinement using the surfaces of metallic nanoparticles often induces permanent structural changes from light, even at low intensities. Here, we report a robust and simple technique to exploit crystal facets and their atomic boundaries to prevent the hopping of atoms along and between facet planes. Avoiding X-ray or electron microscopy techniques that perturb these atomic restructurings, we use elastic and inelastic light scattering to resolve the influence of crystal habit. A clear increase in stability is found for {100} facets with steep inter-facet angles, compared to multiple atomic steps and shallow facet curvature on spherical nanoparticles. Avoiding atomic hopping allows Raman scattering on molecules with low Raman cross-section while circumventing effects of charging and adatom binding, even over long measurement times. These nanoconstructs allow the optical probing of dynamic reconstruction in nanoscale surface science, photocatalysis, and molecular electronics.

Abstract
There has been an ongoing quest to optimize the materials used to build plasmonic devices: first the elements were investigated, then alloys and intermetallic compounds, later semiconductors were considered, and, most recently, there has been interest in using more exotic materials such as topological insulators and conducting oxides. The quality of the plasmon resonances in these materials is closely correlated with their structure and properties. In general gold and silver are the most commonly specified materials for these applications but they do have weaknesses. Here, it is shown how, in specific circumstances, the selection of certain other materials might be more useful. Candidate alternatives include Tix N, VO2 , Al, Cu, Al-doped ZnO, and Cu-Al alloys. The relative merits of these choices and the many pitfalls and subtle problems that arise are discussed, and a frank perspective on the field is provided.
