Der volle Inhalt der QuelleHemos estudiado la dependencia con la temperatura de la luminiscencia generada por nanopartículas dieléctricas dopadas con iones lantánido que pueden ser usadas en nanotermometría luminiscente. Hemos analizado nuevos materiales con emisión en el rango del visible del espectro electromagnético, incluyendo Ho,Yb:KLu(WO4)2 y Ho,Tm,Yb:KLu(WO4)2, así como nanopartículas core-shell de Er,Yb:GdVO4@SiO2. También hemos desarrollado un nuevo método de síntesis solvotermal asistido por microondas para nanopartículas de Er,Yb:NaYF4, que opera a temperaturas más bajas y tiempos de reacción más cortos que los métodos convencionales. Hemos utilizado nanotermometría basada en la medida de tiempos de vida media radiativa en nanoparticulas up-conversoras de Er,Yb:NaY2F5O para la determinación de temperatura en sistemas biológicos, así como la determinación de temperatura por el cambio de color de la emisión de nanopartículas de Tm,Yb:GdVO4@SiO2. Finalmente, hemos desarrollado un sistema de nanotermometría luminiscente simple y compacto que va a permitir acercar la nanotermometría luminiscente al entorno médico e industrial. Hemos analizado también la nanotermometría luminiscente en la región del infrarojo cercano. El Nd:KGd(WO4)2 muestra potencial como nanotermómetro luminiscentes en esta región para sistemas biológicos, con una profundidad de penetración de 1 cm en tejidos biológicos. Los iones Er3+ y Tm3+ muestran bandas de emisión eficientes en esta región que pueden utilizarse para nanotermometría luminiscente en sistemas biológicos. Las nanopartículas de Tm,Yb:GdVO4@SiO2, con emisiones localizadas en la primera ventana biológica, presentan una elevada sensitividad térmica y se han internalizado en células HeLa. Finalmente, hemos mostrado la multifuncionalidad de las nanopartículas de Ho,Tm:KLu(WO4)2 que actúan como nanotermómetros, agentes fototérmicos y marcadores biológicos. También hemos determinado la eficiencia de conversión fototérmica del grafeno y derivados, calentadores eficientes para el tratamiento de diversas enfermedades incluido el cáncer, y hemos desarrollado un nuevo método para determinar esta eficiencia de conversión utilizando una esfera integradora, un método que puede extenderse a otros agentes fototérmicos.
We studied the temperature dependence of the luminescence generated by dielectric nanoparticles doped with lanthanide ions to be used in luminescence nanothermometry. New materials emitting in the visible range of the electromagnetic spectrum, including Ho,Yb:KLu(WO4)2 and Ho,Tm,Yb:KLu(WO4)2 and Er,Yb:GdVO4@SiO2 core-shell nanoparticles have been analyzed for these purposes. Moreover, we developed a new and greener microwave-assisted solvothermal synthesis method for Er,Yb:NaYF4 nanoparticles that operates at lower temperatures and shorter reaction times than conventional methods. We used lifetime-based nanothermometry in upconversion Er,Yb:NaY2F5O nanoparticles for temperature determination in biological systems, and the change of color of the emission generated in Tm,Yb:GdVO4@SiO2 core-shell nanoparticles as a function of temperature. Furthermore, we developed a simple and compact setup that would approach luminescence nanothermometry to the real practical applications in medical and industrial environments. We also explored luminescence nanothermometry in the near infrared region of the electromagnetic spectrum. Nd3+-doped KGd(WO4)2 nanoparticles show potentiality as a luminescent nanothermometer in this region for biological systems, with a penetration depth of 1 cm in biological tissues. Er3+ and Tm3+ ions doped in different matrices have shown also efficient emission bands lying in the short-wavelength infrared region that can be used for luminescence thermometry in biological systems. Also, Tm3+,Yb3+:GdVO4@SiO2 core-shell nanoparticles with emissions located in the first biological window are presented as highly thermal sensitive nanothermometers and have been efficiently internalized in the HeLa cells. Finally, the multifunctionality of Ho3+ and Tm3+ co-doped KLu(WO4)2 nanoparticles has been shown, acting as nanothermometers, photothermal agents and biolabels for bioimaging. Also, we determined the photothermal conversion efficiency of graphene and graphene oxide, efficient heaters for the treatment of several diseases including cancer, and developed a new method for determining their photothermal conversion efficiency by using an integrating sphere, a method that can be extended to other photothermal agents.

Der volle Inhalt der QuelleBiological thermal modifications are common events during abnormal cellular metabolic activities. Indeed, thermal aberrations – such as an increase in local tissue temperature – are directly related to the detection of inflamed areas, the presence of tumors, or other diseases. In addition to contributing to the diagnosis of diseases, the determination of local temperature in biological systems can also help with their treatment. For instance, in hyperthermia, the increase in temperature must be induced in tumor tissues up to cytotoxic levels in order to kill cancer cells and therefore, it assists in the cancer treatment. However, the increase in temperature must be carried out in a controlled and well-localized manner to target cancer cells, while avoiding overheating of surrounding healthy tissue. Furthermore, to determine such biological aberrations, temperature variations must be accurately determined. The thermometric performance of the nanothermometers was determined by calculating the relative thermal sensitivity (S_r) using the ratiometric luminescence intensity approach. Furthermore, our study made it possible to raise some hypotheses that can effectively contribute to the thermometric performance of thermal probes. We use the technique of the intensity ratio of two luminescence peaks for which the values of S_r can be optimized by co-doping the nanocrystals with two, or more, Ln3+ ions and by using oxide matrices presenting different phonon energies. Thus, due to its generic nature and synthesis flexibility, the Pechini method was chosen to synthesize several oxide matrices, Y2O3, Y2Ge2O7, Y3Al5O12 (YAG), Y3BO6 and YBO3. The nanocrystals were firstly monodoped with Nd3+ and posteriorly, codoped with Nd3+ -Yb3+ to improve the thermal probe properties within the biological windows of near infrared. In addition, we optimized the doping concentrations in the host matrices for greater efficiency in luminescence detection in biological organisms. We experimentally observed that Sr values are strongly impacted to the phonon energy of the matrix. We analyzed that by Nd3+ -Yb3+ codoping the thermometric performance of nanocrystals is improved compared to nanocrystals mono doped with Nd3+. Our study of different oxides shows that the YAG and Y2O3 matrices are the most promising matrices for the luminescence nanothermometry in vivo application. Lastly, YAG individual nanocrystals (non-agglomerated as in the case of Pechini syntheses) of size 60 nm and controlled morphology were obtained in solution by the solvothermal method to advance in further studies in biological applications. We observed that the YAG nanothermometers suitable for the purpose have a S_r equal to 0.47 %·K-1 and a thermal resolution of 0.3 K. In vivo experimental tests are required to validate the findings of this study; however, our results obtained on the performance of YAG: Nd3+ -Yb3+ nanocrystals has been showing high potential for in vivo applications of ratiometric luminescence nanothermometry

Der volle Inhalt der QuelleEl desarrollo de nanotermómetros luminiscentes de no contacto basados en iones lantánidos para ser usados como herramientas de diagnóstico precisas, eficientes y rápidas, propiedades atribuidas a su versatilidad, estabilidad y perfiles de banda de emisión estrechos, ha llevado a la sustitución de las sondas térmicas de contacto convencionales. La aplicación de nanopartículas dopadas con lantánidos como nanosensores de temperatura, excitados con luz ultravioleta, visible o infrarroja cercana, y la generación de emisiones en las regiones espectrales de las ventanas biológicas: I-BW (650 nm-950 nm), II-BW (1000 nm -1350 nm), III-BW (1400 nm-2000 nm) y IV-BW (centrada en 2200 nm), está creciendo notablemente debido a ventajas como la reducción de la fototoxicidad y el fotoblanqueo, un mejor contraste de imagen y una mayor profundidad de penetración en tejidos biológicos. Entre estas ventanas biológicas, la III-BW permite lecturas térmicas más profundas dentro de tejidos biológicos específicos, atribuidas a una mayor profundidad de penetración debido a la reducción de la absorbancia y la dispersión en comparación con las otras ventanas biológicas. Sin embargo, la termometría de luminiscencia en este régimen espectral se ha explorado poco. Aquí, hemos sintetizado y caracterizado materiales luminiscentes dopados con Ho3+ y Tm3+ con emisiones ubicadas en la III-BW para su aplicación como termómetros luminiscentes y agentes fototérmicos. Hemos utilizado partículas de KLu(WO4)2 y Y2O3 dopadas con Ho3+ y Tm3+ como posibles agentes fototérmicos automonitorizados capaces de liberar calor y determinar la temperatura simultáneamente. Para su síntesis, hemos adaptado métodos solvotermales (autoclave convencional y asistido por microondas) y químicos húmedos (descomposición térmica y maduración digestiva). Para finalizar, hemos aprovechado la peculiar configuración electrónica y las características morfológicas de las nanopartículas de Y2O3 para aplicarlas como emisores de luz blanca y como agentes antioxidantes ex vivo.
The development of non-contact luminescent lanthanide nanothermometers as accurate, efficient and fast diagnostic tools, attributed to their versatility, stability and narrow emission band profiles, have led to the replacement of the conventional contact thermal probes. The application of lanthanide doped nanoparticles as temperature nanosensors, excited with ultraviolet, visible or near infrared light, and the generation of emissions lying in the biological windows spectral regions: I-BW (650 nm-950 nm), II-BW (1000 nm-1350 nm), III-BW (1400 nm-2000 nm) and IV-BW (centered at 2200 nm), is notably growing due to the advantages of reduced phototoxicity and photobleaching, better image contrast and deeper penetration depths into biological tissues. Among these biological windows, the III-BW allows for deeper thermal readings within specific biological tissues, attributed to a higher penetration depth due to the reduction of absorbance and scattering when compared to the other biological windows. Nevertheless, luminescence thermometry in this spectral regime is randomly explored. Here, we synthesized and characterized luminescent Ho3+ and Tm3+ doped materials with emissions located in the III-BW for their application as luminescent thermometers and photothermal agents. We explored Ho3+ and Tm3+ doped KLu(WO4)2 and Y2O3 particles as potential self-assessed photothermal agents able to release heat and determine temperature simultaneously. For their synthesis, we adapted solvothermal (microwave-assisted and conventional autoclave) and wet-chemical (thermal decomposition and digestive ripening) methods. To conclude, we took profit of the peculiar electronic configuration and morphological characteristics of the Y2O3 nanoparticles to apply them as white light emitters and as ex-vivo antioxidant agents.

Der volle Inhalt der QuelleThe thesis work focuses on the development of multifunctional core/shell nanoplatforms including a functional core acting as a nanothermometer encapsulated in a PMO-type mesoporous hybrid silica layer. The elaboration of the systems was initially carried out according to the strategy of a mesoporous hybrid silica deposition on a silica-based condensed core ("hard template" strategy). A fundamental study of the structure, chemical nature and size of the shell is conducted using a multi-scale experimental approach. The nano-object size modulation in a range between 50 and 500 nm approximately has been demonstrated, as well as the modulation of the chemical composition based on the use of different bridged organosilane precursors. The results revealed that the organization of the mesopores of the layer is conditioned by the supramolecular interactions between organic substructures of the hybrid silica. The elaboration of a photoluminescent functional core doped with rare earths (β-NaYF4: Yb3+, Er3+) was then carried out, followed by the deposition of a hybrid layer in order to obtain multishell systems. These systems have been modified to introduce a hollow space between the two phases. The thermometric performance of the functional nanoparticles as a function of the confinement type were studied in detail on the basis of their photoluminescence response. The evaluation of the performance of the resulting nanothermometers is encouraging for applications in the biological field
