چکیده

Hollow/porous nanoparticles, including nanocarriers, nanoshells, and mesoporous materials have applications in catalysis, photonics, biosensing, and delivery of theranostic agents. Using a hierarchical template synthesis scheme, we have synthesized a nanocarrier mimicking a golf ball, consisting of (i) solid silica core with a pitted gold surface and (ii) a hollow/porous gold shell without silica. The template consisted of 100 nm polystyrene beads attached to a larger silica core. Selective gold plating of the core followed by removal of the polystyrene beads produced a golf ball-like nanostructure with 100 nm pits. Dissolution of the silica core produced a hollow/porous golf ball-like nanostructure.

Capturing electrochemically evolved nanobubbles by electroless deposition. A facile route to the synthesis of hollow nanoparticles.

Gas evolution during electrochemical deposition has long been regarded as undesired and deliberately suppressed. Here, we show a new role of electrochemically evolved hydrogen bubbles, serving as both templates and reducing agent to form hollow Au nanoparticles via electroless deposition. Hollow gold nanoparticles with a complete nanocrystalline shell and a 50 nm hollow core were fabricated. By...

Construction of the finite-element models of golf balls and simulations of their collisions

The purpose of this study is to construct a finite-element (FE) model of golf balls with hyperelasticity and viscoelasticity and to devise a method for construction of FE ball models by investigating the relationship between the material properties and the behaviour of the golf ball during and after impact. As for the material model of the FE ball model, the Mooney–Rivlin model and the three-el...

Self-assembled nano-balls released from multistage vector for cancer therapy.

The efficacy of cancer drugs is often compromised due to the existence of biological barriers such as nonspecific distribution, hemorheological flow limitation and endothelial extravasation, impaired delivery across tumor cell membranes and tissue, and multidrug resistance. To overcome these obstacles, Xu et al developed an injectable nanoparticle generator platform to negotiate with the biolog...

Hollow spherical nucleic acids for intracellular gene regulation based upon biocompatible silica shells.

Cellular transfection of nucleic acids is necessary for regulating gene expression through antisense or RNAi pathways. The development of spherical nucleic acids (SNAs, originally gold nanoparticles functionalized with synthetic oligonucleotides) has resulted in a powerful set of constructs that are able to efficiently transfect cells and regulate gene expression without the use of auxiliary ca...
