Journal ArticleDOI
Anisotropic growth-induced synthesis of dual-compartment Janus mesoporous silica nanoparticles for bimodal triggered drugs delivery.
Xiaomin Li,Lei Zhou,Yong Wei,Ahmed Mohamed El-Toni,Ahmed Mohamed El-Toni,Fan Zhang,Dongyuan Zhao +6 more
TL;DR: The dual-compartment Janus mesoporous silica nanocomposites can be further applied into nanobiomedicine for heat and NIR light bimodal-triggered dual-drugs controllable release and realizes significantly higher efficiency for cancer cell killing compared to that of the single- Triggered drugs delivery system.
Journal ArticleDOI
Spatially Confined Fabrication of Core−Shell Gold Nanocages@Mesoporous Silica for Near-Infrared Controlled Photothermal Drug Release
Jianping Yang,Dengke Shen,Lei Zhou,Wei Li,Xiaomin Li,Chi Yao,Rui Wang,Ahmed Mohamed El-Toni,Fan Zhang,Dongyuan Zhao +9 more
TL;DR: In this article, a novel multifunctional near-infrared (NIR)-stimulus controlled drug release system based on gold nanocages as photothermal cores, mesoporous silica shells as supporters to increase the anticancer drug loading and thermally responsive poly(N-isopropylacrylamide) (PNIPAM) as NIR-stimuli gatekeepers (Au-nanocage@mSiO2@ PNIPAM).
Journal ArticleDOI
Design, synthesis and applications of core–shell, hollow core, and nanorattle multifunctional nanostructures
Ahmed Mohamed El-Toni,Ahmed Mohamed El-Toni,Mohamed A. Habila,Joselito P. Labis,Joselito P. Labis,Zeid A. ALOthman,Mansour Alhoshan,Ahmed A. Elzatahry,Fan Zhang +8 more
TL;DR: The fabrication of nanomaterials that have the combined properties of a core-shell structure with that of a hollow one has resulted in the creation of a new and important class of substances, known as the rattle core- shell nanoparticles, or nanorattles.
Journal ArticleDOI
In Vivo High-resolution Ratiometric Fluorescence Imaging of Inflammation Using NIR-II Nanoprobes with 1550 nm Emission.
TL;DR: This study develops a NIR-IIb (1500-1700 nm) emissive nanoprobe for high-resolution ratiometric fluorescence imaging in vivo and demonstrates the superior spatial resolution of 1550 nm to a penetration depth of 3.5 mm in a scattering tissue phantom.
Journal ArticleDOI
Anisotropic Encapsulation-Induced Synthesis of Asymmetric Single-Hole Mesoporous Nanocages
Xiaomin Li,Lei Zhou,Yong Wei,Ahmed Mohamed El-Toni,Ahmed Mohamed El-Toni,Fan Zhang,Dongyuan Zhao +6 more
TL;DR: The release of the dual-sized guests can be well controlled independently by heat and near-infrared (NIR) light with the assistance of NIR to ultraviolet/visible (UV/vis) optical properties of upconversion nanoparticles and heat-sensitive phase change materials.
