Preparation and Applications of Carbon‐Based Fluorescent Nanothermometers

Abstract: In recent years, carbon‐based fluorescent nanomaterials have been developed rapidly in biology and biomedicine due to their high optical absorptivity, adjustable fluorescent emission, chemical stability, well biocompatibility, and low toxicity. Their applications in temperature sensing have become one of the research hotspots. In this review, the authors summarize and sort out the carbon‐based fluorescent nanothermometers in the following work: 1) the types and temperature‐response mechanism of carbon‐based fl… Show more

“…The images demonstrate that with the increase in temperature, the emission intensity visibility decreases gradually, which is in accordance with the emission spectra. PL quenching in carbon materials can be described by either an aggregation-induced phenomenon or due to thermal activation of nonradiative states or via phonon contribution . The former is not the case here, as the N-CNS powder is used for temperature-dependent analysis.…”

“…The selection of nanothermometers can cover a series of luminescent temperature-responsive probes, including fluorescent small molecules, fluorescent proteins, quantum dots (QDs), lanthanide-ion-doped UCNPs, vacancy-containing nanodiamonds, carbon dots, , and polymeric nanoparticles . The operation of these nanothermometers mostly relies on the temperature-dependent fluorescence properties (Figure b), for example, the emission intensity, emission peak shifting, spectral ratio between the different fluorescence bands, lifetime, polarization anisotropy, and electron spin resonance or optically detected magnetic resonance (ODMR).…”

“…Pp/Pc, GQDs, and their hybrids present multiple options to govern their optical, electronic, and magnetic properties via easy and well-established synthetic methods. 39 UV/Vis spectroscopy, electrospray ionization (ESI) and MALTI-TOF mass spectrometry, Raman spectroscopy, elemental analysis, Fourier-transform infrared spectroscopy (FT-IR), 1 H NMR spectroscopy, transmission electron spectroscopy (TEM), and dynamic light scattering (DLS) are used to characterize GQD-Pp/Pc nanohybrid systems. 119 DLS equipment can measure the size and size distribution of nanoporphyrin (NPs).…”

“…[29][30][31][32][33][34][35] GQDs are zerodimensional, sp 2 -hybridized, fluorescent, semiconductor, carbon nanocrystals (typical size range of 3-30 nm), with the graphene lattices arranged in a honeycomb structure and joined via functional chemical groups on the edge/surface. 26,[36][37][38][39] The interactions in GQDs-Pp/Pc 40 system provide new opportunities to achieve several synchronized adsorption conformations, with a change in substrate binding, electronic level alignment, charge-transfer, 29 axial/peripheral ligation (chemical), and magnetic features. 15,41,42 In the pursuit of new applications, the advantage of the systematically tuned functionalization of porphyrinic 43 -GQD complexes also offers customized and intricate supramolecular association 44,45 for the establishment of unique optical, geometrical, and electronic properties in biomimetic systems.…”
