Core/Shell structured nanoparticles for imaging and therapy

Introduction: Nanoparticles have several exciting applications in various fields of biomedicine. It has been found that among different classes of nanoparticles core/shell is most promising for field of nano-medical imaging and therapy due to their distinct advantages. The core/shell type nanoparticles can be generally comprising of two nanoparticles one act as a core (inner ma...

Multicolor Core/Shell-Structured Upconversion Fluorescent Nanoparticles

Near-infrared (NIR)-to-Visible upconversion fluorescent nanoparticles emit visible light upon NIR-light excitation, and are well suited for bioimaging, compared to the commonly used downconversionfluorescentmaterials.Thesenanoparticleshave advantages such as minimum photodamage to living organisms, weak background fluorescence, high detection sensitivity, and high light-penetration depth in tis...

Core-shell Au-Pd nanoparticles as cathode catalysts for microbial fuel cell applications

Bimetallic nanoparticles with core-shell structures usually display enhanced catalytic properties due to the lattice strain created between the core and shell regions. In this study, we demonstrate the application of bimetallic Au-Pd nanoparticles with an Au core and a thin Pd shell as cathode catalysts in microbial fuel cells, which represent a promising technology for wastewater treatment, wh...

Transition-Metal Nitride Core@Noble-Metal Shell Nanoparticles as Highly CO Tolerant Catalysts.

Core-shell architectures offer an effective way to tune and enhance the properties of noble-metal catalysts. Herein, we demonstrate the synthesis of Pt shell on titanium tungsten nitride core nanoparticles (Pt/TiWN) by high temperature ammonia nitridation of a parent core-shell carbide material (Pt/TiWC). X-ray photoelectron spectroscopy revealed significant core-level shifts for Pt shells supp...
