The spectroscopic properties of different infrared-emitting neodymium-doped nanoparticles (LaF3:Nd3+, SrF2:Nd3+, NaGdF4: Nd3+, NaYF4: KYF4: GdVO4: and Nd:YAG) have been systematically analyzed. A comparison the spectral shapes both emission absorption spectra is presented, from which relevant role played by host matrix evidenced. lack a “universal” optimum system for infrared bioimaging discussed, as specific application experimental setup imaging determine nanoparticle to be preferentially...
Abstract Magnetic nanoparticles (M:NPs) are unique agents for in vivo thermal therapies due to their multimodal capacity efficient heat generation under optical and/or magnetic excitation. Nevertheless, transfer from laboratory the clinic is hampered by absence of feedback and influence that external conditions (e.g., agglomeration biological matrix interactions) have on heating efficiency. Overcoming these limitations requires, first, implementation strategies providing sensing M:NPs order...
The activity of small non-photoactive titania nanoparticles against corona viruses emerges due most probably to direct membrane disruption via complexation with phospholipid molecules and their subsequent removal.
Nanomaterials are prospective candidates for the elimination of viruses due to their multimodal mechanisms action. Here, we tested antiviral potential a largely unexplored nanoparticle cerium dioxide (CeO2). Two nano-CeO2 with opposing surface charge, (+) and (-), were assessed capability decrease plaque forming units (PFU) four enveloped two non-enveloped during 1-h exposure. Statistically significant activity towards coronavirus SARS-CoV-2 influenza virus was registered already at 20 mg...
One of the crucial metabolic processes for both plant and animal kingdoms is oxidation amino acid tryptophan (TRP) that regulates growth controls hunger sleeping patterns in animals. Here, we report revolutionary insights into how this process can be crucially affected by interactions with metal oxide nanoparticles (NPs), creating a toolbox plethora important biomedical agricultural applications. Molecular mechanisms TRP–NP were revealed NMR optical spectroscopy ceria titania X-ray...
Encapsulation of gold nanorods together with Nd-doped fluorescent nanoparticles in a biocompatible polymer creates multifunctional nanostructures, whose infrared fluorescence allows their subcutaneous localization biological tissues while also adding the ability to measure temperature from emitted light order better monitor light-to-heat conversion during photothermal therapy.
Data on the synthesis of individual and multicompo- nent oxides from salts with microwave initiation published over last 15 years are analysed.

Tetragonal xenotime-type yttrium orthophosphate (YPO4) Nd3+ doped nanoparticles suitable for biomedical applications were prepared by microwave-hydrothermal treatment. We applied the energy transfer probing based on analysis of kinetics impurity quenching to determine presence and spatial position –OH fluorescence acceptors in impurity-containing nanoparticles. show that 0.1 at% YPO4 is a two stage (ordered disordered) static kinetics, determined direct acceptors. Analyzing ordered stage, we...

We use two water based synthetic approaches to LaF3:Nd3+ nanoparticles (NPs), hydrothermal microwave treatment (HTMW) and co-precipitation (CO) technique, with different temperature of the reaction mixture study correlation between degree crystallinity NPs their fluorescence properties. showed that spectra quenching kinetics can be a powerful tool reveal crystal lattice defects, namely agglomerations dopant ions (Nd3+) OH− positioned in volume doped NPs. found reduced number such defects as...
In this study we investigated the interaction of atmospheric-pressure helium (He) and He/H2 pulsed-discharge plasma with different water solutions. We developed a synthetic path to obtain fairly uniform, small (~2 nm), surfactant-free silver (Ag) nanoparticles (NPs) treatment an AgNO3 solution bipolar pulsed discharge. The colloidal solutions containing Ag NPs are stable for months do not show any agglomeration (the measured zeta potential is −41 mV at pH ~8). adsorption negatively charged...
