Abstract
In an ideal plasmonic surface sensor, the bioactive area, where analytes are recognized by specific biomolecules, is surrounded by an area that is generally composed of a different material. The latter, often the surface of the supporting chip, is generally hard to be selectively functionalized, with respect to the active area. As a result, cross talks between the active area and the surrounding one may occur. In designing a plasmonic sensor, various issues must be addressed: the specificity of analyte recognition, the orientation of the immobilized biomolecule that acts as the analyte receptor, and the selectivity of surface coverage. The objective of this tutorial review is to introduce the main rational tools required for a correct and complete approach to chemically functionalize plasmonic surface biosensors. After a short introduction, the review discusses, in detail, the most common strategies for achieving effective surface functionalization. The most important issues, such as the orientation of active molecules and spatial and chemical selectivity, are considered. A list of well-defined protocols is suggested for the most common practical situations. Importantly, for the reported protocols, we also present direct comparisons in term of costs, labor demand, and risk vs benefit balance. In addition, a survey of the most used characterization techniques necessary to validate the chemical protocols is reported.

Abstract
In this paper, triblock copolymer polyisoprene-block-polystyrene-block-poly(2-vinylpyridine) (PI-b-PS-b-P2VP) micelles containing HAuCl4 were spin-coated on silicon wafers followed by calcination to form gold nanoparticle arrays. Subsequently the surface optical performances of poly(3-hexylthiophene) (P3HT)-coated Au nanoparticle arrays were investigated. The particle size and the interparticle distance of the gold nanoparticle arrays could be controlled by adjusting the molar ratio of HAuCl4 precursor to vinyl pyridine units in PI-b-PS-b-P2VP and the spin speed during spin-coating. The results demonstrated that Au nanoparticle arrays with large nanoparticle size were able to produce strong electromagnetic field enhancement. Furthermore, the ratio of average particle size to average interparticle distance increased with decreasing spin speed, resulting in strong electromagnetic field enhancement for metal-enhanced fluorescence (MEF) and surface-enhanced Raman scattering (SERS).

Abstract
Owing to their applications in biodetection and molecular bioimaging, near-infrared (NIR) fluorescent dyes are being extensively investigated. Most of the existing NIR dyes exhibit poor quantum yield, which hinders their translation to preclinical and clinical settings. Plasmonic nanostructures are known to act as tiny antennae for efficiently focusing the electromagnetic field into nanoscale volumes. The fluorescence emission from NIR dyes can be enhanced by more than thousand times by precisely placing them in proximity to gold nanorods. We have employed polyelectrolyte multilayers fabricated using layer-by-layer assembly as dielectric spacers for precisely tuning the distance between gold nanorods and NIR dyes. The aspect ratio of the gold nanorods was tuned to match the longitudinal localized surface plasmon resonance wavelength with the absorption maximum of the NIR dye to maximize the plasmonically enhanced fluorescence. The design criteria derived from this study lays the groundwork for ultrabright fluorescence bullets for in vitro and in vivo molecular bioimaging.

Abstract
The aim of this study was to investigate the effect of gold nanoparticle (Au NP)-induced surface plasmons on the performance of organic photovoltaics (OPVs) that consist of copper phthalocyanine and fullerene as the active materials. The photon absorption can be enhanced by immobilization of surfactant-stabilized Au NPs on a self-assembled monolayer-modified indium tin oxide (ITO) electrode, and thus, the photocurrent as well as the power conversion efficiency (PCE) of these OPVs can be improved. Varying the density of the immobilized Au NPs in the devices provided no significant variation in the charge mobility but it did enhance the photocurrent. In addition, device simulation results demonstrated that the improvement in photocurrent was due to the enhancement of light absorption and the increase in charge separation, which was facilitated by the Au NPs. Overall, we attributed the improvement in PCE of OPVs to a localized surface plasmon resonance effect generated by the Au NPs.

Abstract
In this paper, a novel core-shell hybrid nanoparticle with a silver core and cross-linked poly(3-acrylamidephenylboronic acid-co-acrylic acid) shell (Ag@PAPBA-PAA) was reported. The prepared hybrid nanoparticles can exhibit good responsiveness to the glucose concentration and pH of the environment and exhibit a responsive swelling and shrinking behavior. Tuned by the glucose concentration or pH, a swelling of up to 15.0 nm thickness of the hybrid nanoparticle shell can be observed. These unique responsive properties can be employed to tune the metal-enhanced fluorescence (MEF) effects of the incorporated Ag cores. The fluorescence of adsorbed positively charged porphyrin molecules (Por(4+)) shows good sensitivity to the glucose concentration and pH with an enhancement of up to about 1.8-fold. These functional hybrid nanoparticles with tunable MEF effects show a great potential application in the fields of responsive fluorescent sensing and detection.
