A CNT-AuNP hybrid has been synthesized through the Michael addition reaction between thiol-functionalized single-wall CNT and small water-soluble Maleimide-AuNP. The resilience and stability of this hybrid nanosystem is ensured by a covalent bond linking the nanoparticle to the CNT and by the fact that the functionalization reaction involves the organic shell of the AuNP and not its metallic core.

Virus-surface-mimicking decoration of deoxyribonucleic acid (DNA)-entrapped polymeric nanoparticle with AuNPs is demonstrated to lead to enhanced cellular uptake, improved gene transfection, and particularly efficient near-infrared photothermal therapy that cannot be achieved by both of them separately. This hybrid nanosystem represents a novel paradigm of multipurpose organic-inorganic nanopla...

A quantum nanosystem (such as a quantum dot, nanowire, superconducting nanoparticle, or superfluid nanodroplet) involves widely separated characteristic lengths. These lengths range from the average nearest-neighbor distance between the constituent fermions or bosons, or the lattice spacing for a conducting metal, to the overall size of the quantum nanosystem (QN). This suggests the wave functi...

This study describes formation of an actively and passively targeted, water-soluble drug delivery system (DDS) which contains doxorubicin (DOX). The system comprises two biocompatible and biodegradable polymers: poly-γ-glutamic acid (PGA) and chitosan (CH). Self-assembly of these biopolymers in aqueous medium results stable nanoparticles (NPs) with a hydrodynamic size of 80-150 nm and slightly ...

A new drug delivery system, based on mesoporous silica nanoparticles gated by carboxylatopillar[5]arene-modified gold nanoparticles, has been fabricated, which demonstrated good responses to competitive binding and temperature variation. This multifunctional nanosystem combines the excellent characteristics of two kinds of nanoparticles and utilizes a supramolecular host-guest approach for on-d...

l-Dopa@MSNs based on the concept of drug-structure-directing agents were successfully prepared and proved to be programmed oral l-Dopa release nanosystem pH responsive for treatment Parkinson's disease.

Smart drug delivery nanosystem is significant for tumor treatments due to its possibility of temporally, spatially, and dose-controlled release. However, the therapeutic efficacy often compromised in cancer treatment as enrichment agents reticuloendothelial system. Herein, doxorubicin (DOX) loaded biomimetic with macrophage cell membrane (MCM) camouflaged, MnFe2O4-DOX-MCM nanocube (NC), develop...
