Emerging advances in plasmonic nanoassemblies for biosensing and cell imaging

Light‐Responsive Nanoassemblies: Advancing Biomedical Innovation

“…[5] The preparation of nanoassemblies can be generally categorized into two different approaches namely the top-down approach and bottom-up approach. [6] Briefly, the top-down approach utilizes fabrication methods such as lithography and laser ablation in combination with a substrate to create nanoparticles. On the other hand, the bottom-up approach constructs nanoassemblies via the selfassembly of small molecules.…”

Plasmonic porous micro- and nano-materials based on Au/Ag nanostructures developed for photothermal cancer therapy: challenges in clinicalization

“…Generally, these plasmonic nano assemblies possess many advantages compared to individual AuNPs, such as stronger electromagnetic field, more functionality, more flexible responsiveness, and wider applications. 53 In a recent study, a phosphorescent gold( i ) complex emitted white light phosphorescence. Here, the molecular packing, which was related to the emission wavelength and intensity, was determined by the Au–Au bonds in the trimeric gold( i ) complex, confirming their presence as a prerequisite in the synthesis of novel chromophores.…”

Mode-Selective Plasmon Coupling between Au Nanorods and Au Nanospheres

“…Many research groups, including our group, primarily investigated plasmon coupling that occurs between spherical AuNPs (AuNSs). − We assembled AuNSs into dimers, core–satellite nanostructures, − or core–satellite–satellite hierarchical nanostructures in a controlled fashion. Systematic changes in the interparticle distances using molecular linkers and measurements of the consequent plasmon coupling allowed us to gain insight into the nature of plasmon coupling.…”
