The theory of dynamic conductivity of nanosystem is developed within the model of rectangular potentials and different effective masses of electron in open three-barrier resonance-tunnel structure in a constant homogeneous electric field. The application of this theory for the improvement of operating characteristics of quantum cascade laser active region (for the experimentally investigated In...

Abstract The influence of the plasmon three spherical metal nanoparticles (MNPs) on semiconductor quantum dot (SQD) having external fields is analyzed. density matrix equations are modified for description optical properties SQD-MNPs nanosystem. We study theoretically role plasmon–exciton dipole coupling in investigate dependence nanosystem position MNPs with respect to SQD as well material par...

We report here the construction of a bacteriophage M13-templated supramolecular nanosystem, i.e. M13-β-CD/Ada-FITC/Ada-RhB, which can be used as effective ratiometric fluorescent sensors for intracellular sensing.

Synthesis, characterization and evaluation of transferrin-decorated mesoporous silica-coated silver nanoparticles as a novel hemocompatible core@shell nanosystem for selective targeting apoptosis induction in cancer cells.

objective: in order to improve the water solubility and bioavailability of curcumin in cancer therapy, we prepared and tested a novel waterborne cationic polyurethane (pu) as a nano-carrier for curcumin loading (cu-pu). we studied the effect of this prepared nano-drug on melanoma (f10b16) and fibroblasts cells (l929). methods: morphology, size and cell internalization ability of the prepared n...

The applications of photodynamic therapy (PDT) are usually limited by photosensitizers' side effects and singlet oxygen's short half-life. Herein, a mitochondria-targeted nanosystem is demonstrated to enhance the PDT efficacy by releasing a bio-precursor of photosensitizer under two-photon irradiation. A phototriggerable coumarin derivative is first synthesized by linking 5-aminolevulinic acid ...

Recently, functional therapies targeting a specific organ without affecting normal tissues have been designed. The use of magnetic force to reach this goal is studied in this work. Previously, we demonstrated that nanocarriers based on magnetic nanoparticles could be directed and retained in the lungs, with their gene expression under the control of a promoter activated by a magnetic field. Mag...

We present a reconstituted lipoprotein-based nanoparticle platform comprising a curcumin fluorescent motif and an NIR responsive gold core. This multifunctional nanosystem is successfully used for aggregation-dependent fluorescence detection and photothermal disassembly of insoluble amyloid aggregates.
