Y2O3:Nd3+ nanocrystals as ratiometric luminescence thermal sensors operating in the optical windows of biological tissues

Fluorescence Intensity Ratio‐based temperature sensor with single Nd3 + :Y2O3 nanoparticles: Experiment and theoretical modeling

“…Both papers work with Y 2 O 3 nanopowders, albeit not in the single NP level. The highest value for S R found in the literature is 1.59% between 4 FI 9/2 and 4 FI 9/2 transitions reported by [33]. The value of S R is comparable to the ones found in similar Y 2 O 3 based systems.…”

Ag2S Nanoheaters with Multiparameter Sensing for Reliable Thermal Feedback during In Vivo Tumor Therapy

“…[15][16][17][18][19][20] Recent works, however, have raised serious concerns about the reliability of sub-tissue thermal measurements based on luminescent nanothermometers and, therefore, also on S-MPThs. [21][22][23][24] It has been demonstrated how the non-homogeneous transmission of tissues can induce relevant spectral distortions and lead to erroneous thermal readouts that could be as large as 10 °C. [25][26][27][28] As such, previous results provided by S-MPThs in literature have been put in doubt.…”

Biological Deep Temperature Imaging with Fluorescence Lifetime of Rare-Earth-Doped Ceramics Particles in the Second NIR Biological Window

“…There is considerable interest in the development of temperature measurements for use in biomedicine since conventional contact thermometries, such as thermocouples and thermometers, are unsuitable for remote temperature measurement 1 . Because temperature is highly important for controlling various biological functions, including growth 2 , response 3 , and cell division 4 , the development of contactless thermometries is important to visualize dynamic thermal changes in vivo and is also necessary for thermal therapies 5–7 .…”
