Summary: Increasing attention is being focused on malignant bone tumors originating from postoperative recurrence and bone defect problems. The urgent need for a multi-functional platform to achieve efficient tumor treatment and bone regeneration has prompted the design of a multifunctional nanoparticle of copper sulfide-modified Ti3C2TX MXene decorated with dopamine (PDA). These nanoparticles demonstrate excellent photothermal properties and anti-tumor ability, rapidly killing osteosarcoma cells (Saos-2 cells) within 10 minutes under 808 nm laser irradiation by combining photothermal and photodynamic effects. Furthermore, the PDA modification provides the nanoparticles with favorable osteogenic activity.

Summary: Phototherapy (PT), including photodynamic therapy (PDT) and photothermal therapy (PTT), has made significant advancements in antitumor and antiinfection therapy. Sonodynamic therapy (SDT) has gained attention as a novel noninvasive therapy with deeper penetration depth, fewer side effects, and non-phototoxicity than PT. Combining PT with SDT in a dualmodel therapy with advanced sensitizers overcomes the limitations of both methods and shows higher efficacy. Additionally, the integration of photo-diagnosis modality allows visualization of the treatment process in a way that SDT combined with other therapies cannot achieve.

Summary: This article demonstrates the controllable synthesis of low-phonon-energy KPb2X5 (X=Cl, Br) nanoparticles and the ability to tune nanocrystal phonon energies as low as 128 cm(-1). KPb2Cl5 nanoparticles are moisture resistant and can be efficiently doped with lighter lanthanides. The low phonon energies of KPb2X5 nanoparticles promote upconversion luminescence from higher lanthanide excited states and enable highly nonlinear, avalanche-like emission from KPb2Cl5 : Nd3+ nanoparticles. The realization of nanoparticles with tunable, ultra-low phonon energies facilitates the discovery of nanomaterials with phonon-dependent properties, precisely engineered for applications in nanoscale imaging, sensing, luminescence thermometry and energy conversion.

Summary: Photonavalanching nanoparticles (ANPs) with highly nonlinear upconverted emission have great potential for subdiffraction imaging, nanoscale sensing, and optical computing. We use Gd3+-assisted energy migration to tune the emission wavelengths of Tm3+-sensitized ANPs and generate highly nonlinear emission from Eu3+, Tb3+, Ho3+, and Er3+ ions. The upconversion intensities of these spectrally discrete ANPs scale with a nonlinearity factor s = 10-17 under 1064 nm excitation at power densities as low as 7 kW cm(-2). This strategy can be extended to fluorophores adjacent to ANPs, as shown with CdS/CdSe/CdS core/shell/shell quantum dots.

Summary: In recent years, there has been significant interest in infrared emitting luminescent nanothermometers due to their potential for new diagnosis and therapy procedures. However, concerns have been raised regarding their reliability, as tissues can induce spectral distortions even in the commonly used second biological window. In this study, the effectiveness of shifting the operation range of these nanothermometers to the third biological window is demonstrated, showing minimal distortion by tissue and opening the path to reliable luminescence thermometry. Advanced analysis of emission spectra allows for sub-degree thermal uncertainties.

Summary: Near-infrared (NIR) luminescence thermometry is a reliable method for remote thermal sensing and imaging. Lanthanide (Ln(3+))-based nanophosphors are commonly used as NIR nanothermometers, but the combination of Ln(3+) with transition metal (TM) ions can enhance the sensitivity of the thermometric approach. However, there are few examples of luminescence nanothermometers combining both TM and Ln(3+), leaving room for further exploration of these systems.
