In the field of environmental science, efficient removal of organic pollutants and pathogenic bacteria from wastewater using a photocatalytic process that responds to the full spectrum of sunlight is crucial. In this study, a highly effective nanoheterojunction called NaGdF4:Yb,Er@zeolitic imidazolate framework‐8/manganese dioxide (NaGdF4:Yb,Er@ZIF‐8/MnO2, UCZM) was synthesized. This nanoheterojunction exhibits a remarkable ability to respond to the entire range of ultraviolet, visible, and infrared light. Under simulated sunlight, UCZM demonstrated outstanding performance in degrading malachite green dye, with a degradation efficiency of 92.6% within 90 min. Moreover, UCZM completely inactivated both Staphylococcus aureus and Escherichia coli within 20 min under simulated sunlight. Mechanistic studies revealed that NaGdF4:Yb,Er played a crucial role in activating ZIF‐8 and MnO2 through Förster resonance energy transfer, facilitating the photocatalytic process. The formation of a Z‐type heterojunction in UCZM promoted the efficient separation of photogenerated carriers. Furthermore, UCZM exhibited excellent biosafety properties. This study represents the first exploration of a composite material composed of UCNPs, ZIF‐8, and MnO2 for photocatalytic applications. The findings highlight the potential of this novel nanoheterojunction design, which exhibits a full spectral response, for tackling water pollution through efficient photocatalytic degradation of organic pollutants and inactivation of pathogenic bacteria.image

“…The band at 610 cm −1 can be attributed to fluoride lattice, confirming the formation of the fluoride nanocrystals. For PEG-capped nanoparticles, the peaks at around 1638 cm −1 , 1439 cm −1 , and 1084 cm −1 are assigned to the methylene scissoring and C-O-C stretching vibrations of PEG [23]. The appearance of these characteristic peaks of PEG demonstrates that PEG was successfully conjugated on the surface of the nanoparticles.…”

“…Gadolinium trifluoride (GdF 3 ) nanoparticles are excellent host materials and characterized by effective luminescence, high transparency, low phonon energy of ~4.19 kJ/mol, and high chemical and thermal stability [19][20][21][22][23]. The Gd 3+ ions can act as intermediates, allowing energy to migrate over the Gd 3+ sublattice and consequently facilitating the energy transfer to luminescent centers.…”

Herein we report the development of a nanocomposite for X-ray-induced photodynamic therapy (X-PDT) and computed tomography (CT) based on PEG-capped GdF3:Tb3+ scintillating nanoparticles conjugated with Rose Bengal photosensitizer via electrostatic interactions. Scintillating GdF3:Tb3+ nanoparticles were synthesized by a facile and cost-effective wet chemical precipitation method. All synthesized nanoparticles had an elongated “spindle-like” clustered morphology with an orthorhombic structure. The structure, particle size, and morphology were determined by transmission electron microscopy (TEM), X-ray diffraction (XRD), and dynamic light scattering (DLS) analysis. The presence of a polyethylene glycol (PEG) coating and Rose Bengal conjugates was proved by Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TG), and ultraviolet–visible (UV-vis) analysis. Upon X-ray irradiation of the colloidal PEG-capped GdF3:Tb3+–Rose Bengal nanocomposite solution, an efficient fluorescent resonant energy transfer between scintillating nanoparticles and Rose Bengal was detected. The biodistribution of the synthesized nanoparticles in mice after intravenous administration was studied by in vivo CT imaging.

“…Cytotoxicity was observed at UCNP concentrations above 25 μg/mL for which several possible causes have been identified in previous research. For example, Hong et al reported that oleic acid-modified UCNPs are cytotoxic . Aqueous dispersions of UCNPs have been reported to possibly release fluoride and/or lanthanide ions, , the former of which Chang et al reported to be cytotoxic .…”

Bioactuators made of cultured skeletal muscle cells are generally driven by electrical or visible light stimuli. Among these, the technology to control skeletal muscle consisting of myoblasts genetically engineered to express photoreceptor proteins with visible light is very promising, as there is no risk of cell contamination by electrodes, and the skeletal muscle bioactuator can be operated remotely. However, due to the low biopermeability of visible light, it can only be applied to thin skeletal muscle films, making it difficult to realize high-power bioactuators consisting of thick skeletal muscle. To solve this problem, it is desirable to realize thick skeletal muscle bioactuators that can be driven by near-infrared (NIR) light, to which living tissue is highly permeable. In this study, as a promising first step, upconversion nanoparticles (UCNPs) capable of converting NIR light into blue light were bound to C2C12 myoblasts expressing the photoreceptor protein channelrhodopsin-2 (ChR2), and the myoblasts calcium ion (Ca 2+ ) influx was remotely manipulated by NIR light exposure. UCNP-bound myoblasts and UCNP-bound differentiated myotubes were exposed to NIR light, and the intracellular Ca 2+ concentrations were measured and compared to myoblasts exposed to blue light. Exposure of the UCNP-bound cells to NIR light was found to be more efficient than exposure to blue light in terms of stimulating Ca 2+ influx.
