Fabrication of Two-Dimensional Platelets with Heat-Resistant Luminescence and Large Two-Photon Absorption Cross Sections via Cooperative Solution/Solid Self-Assembly.

The combination of solution self-assembly, which enables primary morphological control, and solid self-assembly, which enables the creation of novel properties, can lead to the formation of new functional materials that cannot be obtained using either technique alone. Herein, we report a cooperative solution/solid self-assembly strategy to fabricate novel two-dimensional (2D) platelets. Precursor 2D platelets with preorganized packing structure, shape, and size are formed via the living self-assembly of a donor-acceptor fluorophore and volatile coformer (i.

Development of Binary Coassemblies for Sensitively and Selectively Detecting Gaseous Sarin.

The low sensitivity and poor selectivity of fluorescence sensors for real gaseous sarin detection greatly hinder their real-world applications. In this work, we report the development of a novel fluorophore with an active N-H vibration in the benzimidazole group for the sensitive detection of gaseous sarin. We demonstrate that the interactions between the nucleophilic fluorine atom in sarin and the electrophilic hydrogen atom in the benzimidazole group of the fluorophore can restrict the N-H vibration to yield sensitive fluorescence-enhancing responses.

Rare case report and literature review of intracranial mesenchymal chondrosarcoma.

Intracranial mesenchymal chondrosarcoma (IMC) is a rare primary malignant tumor in the skull, but mostly originates from the abnormal residual chondrocytes in the embryonic period, which grow slowly, and primarily occurs at the junction of the cartilage of the skull base. IMC is difficult to diagnose by preoperative imaging and is easily misdiagnosed. It needs to be differentiated from meningiomas, gliomas, hemangioma, fibroids, etc.

Chemodynamic/photothermal synergistic therapy based on Ce-doped Cu-Al layered double hydroxides.

The combination of chemodynamic therapy (CDT) with photothermal therapy (PTT) is an efficacious strategy in cancer treatment to acquire satisfactory therapy efficiency in the endogenous redox reaction and external laser induction. In this work, we have designed Ce doped Cu-Al layered double hydroxide (CAC-LDH) ultrathin them through a bottom-up synthesis method, and further loaded them with indocyanine green (ICG). The synthesized ICG/CAC-LDH was used as a Fenton-catalyst and photothermal agent.

Multicomponent Transition Metal Dichalcogenide Nanosheets for Imaging-Guided Photothermal and Chemodynamic Therapy.

Transition metal dichalcogenides (TMDs) have received considerable attention due to their strong absorption in the near-infrared (NIR) region, strong spin-orbit coupling, and excellent photothermal conversion efficiency (PCE). Herein, CoFeMn dichalcogenide nanosheets (CFMS NSs) are prepared via facile vulcanization of a lamellar CoFeMn-layered double hydroxide (LDH) precursor followed by polyvinyl pyrrolidone modification (to give CFMS-PVP NSs), and found to show excellent photoacoustic (PA) imaging and synergistic photothermal/chemodynamic therapy (PTT/CDT) performance. The as-prepared CFMS-PVP NSs inherit the ultrathin morphology of the CoFeMn-LDH precursor and exhibit an outstanding photothermal performance with a of 89.

Photoluminescence enhancement of silver nanoclusters assembled on the layered double hydroxides and their application to guanine detection.

Development of the fluorescent and stability-enhanced scheme for silver nanoclusters is challengeable. In the present study, silver nanoclusters stabilized by nuclear fast red sodium salt (NFR) were assembled with MgAl-layered double hydroxide (LDH) nanosheets. The as-prepared films (AgNCs-NFR/LDH UTFs) were confirmed by powder X-ray diffraction (XRD), UV-vis, fluorescence spectra,atomic force microscope (AFM) and scanning electron microscope (SEM).

Fabrication of dual-stimuli responsive films assembled by flavin mononucleotide and layered double hydroxides.

A dual-stimuli responsive strategy is developed for the detection of melamine and temperature. Flavin mononucleotide (FMN) was immobilized onto layered double hydroxide (LDH) nanosheets through a layer-by-layer process. The as-prepared composite films show higher emission intensity, prolonged fluorescence lifetimes and fluorescence responses towards melamine and temperature.
