Cancer Therapy In article number 2202694, Dong-Hyun Kim and co-workers develop reactive oxygen species (ROS)–responsive biodegradable metallic nanoparticles that can be used for various biomedical applications. Given the challenges of non-biodegradability potent inorganic nanoparticles, introduction a ROS-responsive cleavable hierarchical supra-nanostructure provides an exciting opportunity ROS...

In this study, we constructed a novel solid state supramolecular system-the molecular cage ZnOTCPP, based on an inorganic/organic hybrid nanostructure, through the assembly of 5,10,15,20-tetra(3-carboxyphenyl)porphyrin (TCPP) onto the surfaces of ZnO nanorod (NR) arrays. The ZnOTCPP molecular cage exhibited highly selective recognition of 5,10,15,20-tetraphenylporphyrin (TPP) by optical and pho...

Hybrid thin film solar cell based on all-inorganic nanoparticles is a new member in the family of photovoltaic devices. In this work, a novel and performance-efficient inorganic hybrid nanostructure with continuous charge transportation and collection channels is demonstrated by introducing CdTe nanotetropods (NTs) and CdSe quantum dots (QDs). Hybrid morphology is characterized, demonstrating a...

In this study, Eu-coated SiO2 nanoparticles have been prepared, consisting of an interfacial complex of Eu and 1,10-phenanthroline (phen) at the solid surfaces of the SiO2/Eu nanostructures. The as-prepared SiO2/Eu/phen nanoparticles exhibits sharp red emission via energy transfer from the phen to the Eu(III). After sintering at 200 °C in air, the emission is tuned from red to blue. The blue em...

Recent progress in the development of nanostructured inorganic solar cells is reviewed. Nanostructuring of inorganic solar cells offers the possibility of reducing the cost of photovoltaics by allowing smaller amounts of lowergrade photovoltaic semiconductors to be used. Various fabrication methods used to nanostructure traditional photovoltaic semiconductors are detailed and the performance of...

We present a method to increase the stability of DNA nanostructure templates through conformal coating with a nanometer-thin protective inorganic oxide layer created using atomic layer deposition (ALD). DNA nanotubes and origami triangles were coated with ca. 2 nm to ca. 20 nm of Al2O3. Nanoscale features of the DNA nanostructures were preserved after the ALD coating and the patterns are resist...

Helical inorganic nanostructures have received great attention due to their unique structures that could be interesting for both fundamental research and nanodevice applications. Using a tube-in-tube laser ablation chemical vapor deposition (CVD) method with gold nanoparticles as the catalysts, we reported the synthesis of self-assembled kinked In2O3 nanospirals and multikinked nanowires. As-sy...

Bone is an organic-inorganic composite which has hierarchical structuring that leads to high strength and toughness. The nanostructure of bone consists of nanocrystals of hydroxyapatite embedded and aligned within the interstices of collagen fibrils. This unique nanostructure leads to exceptional properties, both mechanical and biological, making it difficult to emulate bone properties without ...

The electronic properties of semiconducting inorganic lead sulfide (PbS) nanocrystals (NCs) and organic linker molecules are dependent on the size NCs as well used ligands. Here, we demonstrate that a weakly binding ligand can be successfully attached to PbS form coupled organic–inorganic nanostructure (COIN) by mixing with strong partner. We use zinc β-tetraaminophthalocyanine (Zn4APc) in comb...
