Effect of surface properties on nanoparticle-cell interactions.
The interaction of nanomaterials with cells and lipid bilayers is critical in many applications such as phototherapy, imaging, and drug/gene delivery. These applications require a firm control overExpand

Surface-structure-regulated cell-membrane penetration by monolayer-protected nanoparticles.
Nanoscale objects are typically internalized by cells into membrane-bounded endosomes and fail to access the cytosolic cell machinery. Whereas some biomacromolecules may penetrate or fuse with cellExpand

A general mechanism for intracellular toxicity of metal-containing nanoparticles† †Electronic supplementary information (ESI) available. See DOI: 10.1039/c4nr01234h Click here for additional data
We demonstrate a general mechanism for the toxicity induced by metal-containing NPs, named “lysosome-enhanced Trojan horse effect”, which provides design rules to engineer safer NPs.

Spontaneous assembly of subnanometre-ordered domains in the ligand shell of monolayer-protected nanoparticles
The properties of materials can be created and improved either by confining their dimensions in the nanoscale or by controlling their nanostructure. We have combined these two concepts, and here weExpand

Determination of nanoparticle size distribution together with density or molecular weight by 2D analytical ultracentrifugation
Nanoparticles are finding many research and industrial applications, yet their characterization remains a challenge. Their cores are often polydisperse and coated by a stabilizing shell that variesExpand

Divalent Metal Nanoparticles
Nanoparticles can be used as the building blocks for materials such as supracrystals or ionic liquids. However, they lack the ability to bond along specific directions as atoms and molecules do. WeExpand

The effect of nanometre-scale structure on interfacial energy.
Natural surfaces are often structured with nanometre-scale domains, yet a framework providing a quantitative understanding of how nanostructure affects interfacial energy, gamma(SL), is lacking.Expand

A Study of the Surface Plasmon Resonance of Silver Nanoparticles by the Discrete Dipole Approximation Method: Effect of Shape, Size, Structure, and Assembly
The surface plasmon resonance (SPR) of silver nanoparticles (AgNPs) was studied with the discrete dipole approximation considering different shapes, sizes, dielectric environments, and supraparticlesExpand

Entropy-mediated patterning of surfactant-coated nanoparticles and surfaces.
We perform atomistic and mesoscale simulations to explain the origin of experimentally observed stripelike patterns formed by immiscible ligands coadsorbed on the surfaces of gold and silverExpand
