Mn2+-doped ZnS nanocrystals with an amine-capping layer have been synthesized and used for the fluorescence detection of ultratrace 2,4,6-trinitrotoluene (TNT) by quenching strong orange Mn2+ photoluminescence. The organic amine-capped can bind TNT species from solution atmosphere acid−base pairing interaction between electron-rich amino ligands electron-deficient aromatic rings. resultant anions bound onto monolayer efficiently quench photoluminescence through electron transfer conductive...
Here we present a simple approach for the fabrication of Pd–Ni alloy nanoparticles embedded in carbon layer on raspberry-like SiO<sub>2</sub> hollow nanocages (SiO<sub>2</sub>@C-PdNi).
Abstract Yolk‐like nano/microparticles with superparamagnetic iron oxide (SPIO) cores and hierarchical nickel silicate (NS) shells, designated yolk SPIO@NS, are fabricated by combining the versatile sol–gel process hydrothermal reaction, involving coating of SPIO particles SiO 2 transformation shells into NS hollow spheres nanostructures. Various yolk/shell nanostructures tunable shell thicknesses core sizes successfully prepared controlling experimental parameters. Au nanoparticles can be...
A facile method was developed to synthesize Fe<sub>3</sub>O<sub>4</sub>/polydopamine (PDA) dual shelled microspheres with a hollow interior.
This work reports a novel Fe3O4@polydopamine/Au/polydopamine core/shell nanocomposite toward magnetically separable nanocatalyst. Because the polydopamine (PDA) layer-sandwiched Au nanocrystals were prepared by layer-by-layer method, content of could be controlled varying shell number (such as burger-like Fe3O4@PDA/Au/PDA/Au/PDA). Fe3O4@PDA/Au/PDA exhibited excellent catalytic activity in reducing p-nitrophenol because substrate penetrate PDA shell. Owing to protection shell, presented...
Flexible ultraviolet (UV) photodetectors have attracted extensive research interest due to their potential applications in personal UV monitoring, electronic eye, anti-UV gloves, and other wearable systems. In this study, we present a highly sensitive flexible photodetector based on an ultrathin GaAs layer that is produced using metal–organic chemical vapor deposition method epitaxial lift-off film transfer technology. Device performance analysis reveals the made of 50 nm thick excellent...
Abstract Chemical pollution, pathogenic bacteria, and bacterial biofilms pose significant threats to public health. Although various nanoplatforms with both catalytic antibacterial activities have been developed, creating a remotely controllable nanorobot precise targeting propulsion capabilities remains challenge. This study presents the fabrication of hollow‐structured Fe 3 O 4 @AgAu@polydopamine (PDA) nanosphere, which demonstrated activity superior magnetically enhanced biofilm removal...
In this study, simple-structured wavelength sensors were developed by depositing two back-to-back Au/MAPbI3/Au photodetectors on an MAPbI3 single crystal. This sensor could quantitatively distinguish wavelengths. Further device analysis showed that both possess entirely disparate optoelectronic properties. Consequently, the as-developed accurately incident-light wavelengths ranging from 265 to 860 nm with a resolution of less than 1.5 based relation between photocurrent ratios and incident...
In this work, a MXene@AgPd/polydopamine (PDA) nanosheet with excellent photothermal conversion efficiency was successfully synthesized by simple redox-oxidative polymerization method. Interestingly, AgPd bimetallic nanocrystals sandwiched between MXene and PDA layer have cage-like nanostructure, which is favorable for high catalytic antibacterial performance. Importantly, the MXene@AgPd/PDA exhibits good activity reduction of 4-nitrophenol (1.2 min-1 mg-1) dynamics can be improved about 1.2...
This paper reports an inverted opal fluorescence chemosensor for the ultrasensitive detection of explosive nitroaromatic vapors through resonance-energy-transfer-amplified quenching. The silica film with amino ligands was first fabricated by acid-base interaction between 3-aminopropyltriethoxysilane and surface sulfonic groups on polystyrene microsphere templates. fluorescent dye then chemically anchored onto interconnected porous to form a hybrid monolayer molecules. can efficiently capture...

Antimicrobial materials are expected to be alternatives for antibiotics against multidrug-resistant bacteria. In this paper, non-spherical α-Fe2O3@Au/PDA core/shell nanoparticles with tunable shapes synthesized by a one-step in situ oxidation-redox polymerization method toward near infrared light-responsive antibacterial therapy. The thickness and composition of the Au/PDA hybrid shell can controlled varying concentration HAuCl4 dopamine precursor. Owing wonderful photothermal...
