“…The MS concentration in the dispersion was optimized to yield in deposition of isolated MSs on a smooth Au mirror upon drop-casting. Figure 3d provides correlated SEM, laser confocal (reflectivity at pump laser wavelength of 633 nm) and SERS (intensity at 520.8 ± 1 and 612 ± 1 cm −1 ) image of a single 1.1-µ m-sized Au-Si MS confirming its ability to detect adsorbed analyte molecules at pump intensity ( ≈ 0.3 mW/ µ m 2 ) while preserving the sensor temperature below that of the analyte's thermal decomposition 49 . At such pump intensity, the R6G Raman signal measured from a smooth Au reference is indistinguishable over the noise level.…”

“…The atom economy of the reaction is elevated due to water being the only by-product. Additionally, the moderate reaction temperature used and the thermal stability of the dyes [ 31 , 32 , 33 ] would allow the distillation of impregnation and washing solutions to recover the unreacted dye and ethanol.…”

Having access to safe drinking water is one of the 17 sustainable development goals defined by the United Nations (UN). However, many settlements around the globe have limited access to drinkable water due to non-anthropogenic pollution of the water sources. One of those pollutants is fluoride, which can induce major health problems. In this manuscript, we report on a post synthetic functionalization of metal organic frameworks for the sensing of fluoride in water. The proposed thermal condensation methodology allows for a high yield of functionalization using few steps, reducing reagent costs and generating minimal by-products. We identified a Rhodamine B functionalized Al-BDC-NH2 metal organic framework as one particularly suitable for fluoride detection in water.

“…0.2 mm size), we obtain an estimation of the increase of the temperature during one laser pulse as . Here, N A is the Avogadro number, and C M is a molar heat capacitance of the dye, for which a value C M = 550 J/(K mol), measured for analogous rhodamine dye, was applied. In this estimation, we ignore the reflection of laser radiation and the electromagnetic field enhancement by the sharp metal-coated tip, as well as different correcting factors related with the shape and refraction index of nanohill-like dye structures .…”

Gap-Plasmon-Enhanced High-Spatial-Resolution Imaging by Photothermal-Induced Resonance in the Visible Range

Chemical characterization at the nanoscale is of significant importance for many applications in physics, analytical chemistry, material science, and biology. Despite the intensive studies in the infrared range, high-spatial-resolution and high-sensitivity imaging for compositional identification in the visible range is rarely exploited. In this work, we present a gap-plasmon-enhanced imaging approach based on photothermal-induced resonance (PTIR) for nanoscale chemical identification. With this approach, we experimentally obtained a high spatial resolution of ∼5 nm for rhodamine nanohill characterization and achieved monolayer sensitivity for mapping the single-layer chlorophyll-a islands with the thickness of only 1.9 nm. We also successfully characterized amyloid fibrils stained with methylene blue dye, indicating that this methodology can be also utilized for identification of the radiation-insensitive macromolecules. We believe that our proposed high-performance visible PTIR system can be used to broaden the applications of nanoscale chemical identification ranging from nanomaterial to life science areas.
