Synthesis of Magnetic Luminescent Nanoparticle FeO@LaF:Eu,Ag@APTES@β-CD, a Potential Carrier of Antimicrobial Drug Ciprofloxacin.

FeO@LaF:Eu,Ag hybrid magnetic luminescent nanoparticles (NPs) were synthesized using a simple co-precipitation method and then functionalized with β-cyclodextrin (β-CD) using (3-aminopropyl)triethoxysilane (APTES). The chemical composition, crystalline nature, particle size, and surface morphology of the FeO@LaF:Eu,Ag@APTES@β-CD NPs were investigated, using powder X-ray diffraction, and high-resolution transmission electron microscopy. The uptake and release profiling of the LaF:Eu,Ag@FeO@β-CD NPs for the hydrophilic drug ciprofloxacin, showed 40 and 85% efficiency, respectively.

Improved Surface-Enhanced Raman Scattering Performance of 2D TiCT MXene Embedded in PVDF Film Enabled by Photoinduction and Electric Field Modulation.

In this study, we introduce a synergistic approach to enhance the surface-enhanced Raman scattering (SERS) signal in two-dimensional (2D) MXene through photo-irradiation and electric field modulation. Our methodology involves the integration of 2D TiCT MXene with piezoelectric polyvinylidene fluoride (PVDF) polymer, resulting in the creation of a free-standing, flexible composite film. On this composite film, a thin layer of Au was deposited.

Schottky junction devices by using bio-molecule DNA template-based one dimensional CdS-nanostructures.

Creating a well-defined nanostructure through de-oxyribo nucleic acid (DNA)-nanotechnology, and specifically the development of metal/inorganic semiconductor junctions on DNA-assembled nanostructures, is an emerging research area. Herein, we investigate the electrical properties of biomolecule DNA-template based one-dimensional nanowires (NWs)-CdS/Au and without-template based nanoparticles (NPs)-CdS/Au devices grown on the Indium Tin Oxide (ITO) glass substrates. More importantly, the NWs-CdS/Au device displays a dramatic augmentation of current flow and also a striking change in threshold voltage (~55 mV) in comparison to NPs (~190 mV) and reported bulk-CdS/Au (~680 mV) devices.
