Plasmonic nanomaterials: A versatile phototheranostic platform of cancers

Polydopamine-based plasmonic nanocomposites: rational designs and applications

“…silver (Ag) NPs, have received extensive attention in the field of nanoplasmonics, attributed to their capacity for surfaceenhanced spectroscopies, 3 use in functional optoelectronic devices, 4 energy conversion, 5 photocatalysis, 6 and biomedical applications. 7,8 Nowadays, most plasmon-driven applications rely on plasmonic nanocomposites, i.e., multicomponent nanomaterials composed of plasmonic nanomaterials and other functional materials such as polymers, semiconductors, metal-organic frameworks (MOFs), carbons, biomolecules, and magnetic materials. 9,10 Diverse classes of plasmonic nanocomposites have been demonstrated to render new functionalities to traditional plasmonic NPs.…”

Strategies for Surface Design in Surface Plasmon Resonance (SPR) Sensing

“…Because of this behaviour, the collective oscillations of free electrons increase at a specific frequency. It should be highlighted that plasmons can be excited by incident electromagnetic waves only when the frequency of waves and plasmons coincide [ 68 , 69 ]. Moreover, the sensitivity of LSPR can be influenced by the size of nanoparticles.…”

NIR-IIb fluorescence-image guided synergistic surgery/starvation/chemodynamic therapy: an innovative treatment paradigm for malignant non-small cell lung cancers

“…In contrast, recently we and others have confirmed the NIR-II optical imaging could realize in time in vivo imaging with good spatiotemporal resolution, high sensitivity, deep penetration, large SBR and non-invasiveness, which paves the way for sensitive diagnosis of early-stage microscopic tumors [13][14][15]. Notably, the fidelity of NIR-II optical imaging heavily depends on the brightness of the contrast agents [13][14][15], for which both organic materials (e.g., dyes and conjugated polymers) and inorganic ones (carbon nanotubes, quantum dots, plasm nanoparticles), and lanthanidedoped downconversion nanoparticles (DCNPs) have been developed [16][17][18][19][20]. Among these materials, DCNPs have attracted increasing attention in application of monitoring physiological and pathological processes [16][17][18][19][20][21][22][23][24][25][26].…”

Among these materials, DCNPs have attracted increasing attention in application of monitoring physiological and pathological processes [16][17][18][19][20][21][22][23][24][25][26]. The primary reason is that they could be customized to offer nonphotobleached emission in the transparent NIR-IIb window (1500-1700 nm) with much lower background interference, suppressed scattering and deeper penetration as compared to the vis/NIR-I and even NIR-IIa window (1000-1300 nm) via adjusting their composition and morphology [21][22][23][24].…”
