“…The capability of PNIPAM in tuning SPs has also been harnessed for the dynamic surface-enhanced Raman spectroscopy (SERS) substrates. As shown in Figure 2C, the phase transition of PNIPAM sandwiched between Au nanospheres and Au thin films tunes the plasmonic coupling and thus, the Raman enhancement of probe molecules [64]. Hybrid systems using other types of thermoresponsive polymers have also been demonstrated [65,66].…”

“…The phase transition has been harnessed for AMP through the changes in refractive index of the polymers and/or interparticle coupling [59][60][61][62][63][64]. As demonstrated by Mistsuishi and colleagues (Figure 2A), Au nanoparticles embedded in PNIPAM brushes exhibit thermally controllable peak shifts in the LSPRs due to a refractive index change caused by the phase transition of the polymers [59].…”

“…Since SPs exist at the near field of the nanostructures with a subwavelength skin depth in dielectric materials, 3D organic materials interact with a whole field of SPs [57][58][59][60][61][62][63][64][65][66][67]. As a result, the AMP performances based on 3D organic materials largely depend on the materials' switchability and tunability in the optical properties, as well as the sensitivity of plasmonic nanostructures.…”

Molecular plasmonics explores and exploits the molecule-plasmon interactions on metal nanostructures to harness light at the nanoscale for nanophotonic spectroscopy and devices. With the functional molecules and polymers that change their structural, electrical, and/or optical properties in response to external stimuli such as electric fields and light, one can dynamically tune the plasmonic properties for enhanced or new applications, leading to a new research area known as active molecular plasmonics (AMP). Recent progress in molecular design, tailored synthesis, and self-assembly has enabled a variety of scenarios of plasmonic tuning for a broad range of AMP applications. Dimension (i.e., zero-, two-, and threedimensional) of the molecules on metal nanostructures has proved to be an effective indicator for defining the specific scenarios. In this review article, we focus on structuring the field of AMP based on the dimension of molecules and discussing the state of the art of AMP. Our perspective on the upcoming challenges and opportunities in the emerging field of AMP is also included.

The unique optical properties of plasmon resonant nanostructures enable exploration of nanoscale environments using relatively simple optical characterization techniques. For this reason, the field of plasmonics continues to garner the attention of the biosensing community. Biosensors based on propagating surface plasmon resonances (SPRs) in films are the most well-recognized plasmonic biosensors, but there is great potential for the new, developing technologies to surpass the robustness and popularity of film-based SPR sensing. This review surveys the current plasmonic biosensor landscape with emphasis on the basic operating principles of each plasmonic sensing technique and the practical considerations when developing a sensing platform with the various techniques. The “gold standard” film SPR technique is reviewed briefly, but special emphasis is devoted to the up-and-coming LSPR-based and plasmonically coupled sensor technology.

“…Efficient "click chemistry" reactions have been developed for 30 years to graft surfaces with molecules, macromolecules, metal or inorganic nanoparticles. [6] Among them, Huisgen cycloaddition [7,8], thiol-ene reaction [9], or Diels-Alder cycloadditions [10] are the most used. Recently, a new reaction has been investigated by the community: the nucleophilic aromatic substitution of para-fluorine atom of pentafluorophenyl moeities by a variety of nucleophiles, such as thiols, amines and alcohols.…”

A fast and simple bottom-up methodology is reported to allow, thanks to a spontaneous phenomenon, the grafting of various materials on polymer substrates. In 60 seconds, the inert surface of polystyrene material is converted into a functional platform onto which organic molecules and metal particles can be anchored. A polystyrene (PS) matrix is blended with a small amount of a diblock copolymer additive engineered to both segregate at the material surface and be able to involve chemical reaction. Indeed, poly(penta fluorostyrene) (PSF) contains surface active fluorine atoms and the nucleophuge para-fluorine atom that allow nucleophilic substitution with thiols. Films of blend of PS matrix and PS-b-PSF additive are submitted to a microwave annealing to accelerate the spontaneous surface segregation of fluorine low surface energy atoms. XPS was performed to find that the optimal annealing condition was a treatment at 30 W during 60 seconds. With this procedure, a blend of 5 w% in additive can lead to a surface composed of 13 at% of fluorine atoms corresponding to 55 w% of diblock. The pentafluorostyrene units decorating the surface were used as anchors to immobilize gold nanoparticles via the para-fluoro-thiol click reaction.
