Response to "Critical Assessment of the Evidence for Striped Nanoparticles"

Francesco Stellacci, Quy Ong Khac

Stirling et al., (10.1371/journal.pone.0108482) presented an analysis on some of our publications on the formation of stripe-like domains on mixed-ligand coated gold nanoparticles. The authors shed doubts on some of our results however no valid argument is ...

Size distributions and fractograms of cholesterol-rich lipoprotein nanoparticles for cancer diagnosis

Francesco Stellacci, Quy Ong Khac, Lixia Wei

The present invention relates to a method for the diagnosis of cancer in a sample of cholesterol-rich lipoprotein nanoparticles obtained from a test subject comprising (α) determining the size distribution or the fractogram in chromatography of the cholest ...

Thioether-Functionalized Quinone-Based Resorcin[4]arene Cavitands: Electroswitchable Molecular Actuators

Jovana Milic, Quy Ong Khac

The utility of molecular actuators in nanoelectronics requires activation of mechanical motion by electric charge at the interface with conductive surfaces. We functionalized redox-active resorcin[4]arene-quinone cavitands with thioethers as surface-anchor ...

Quantitative Analysis of Scanning Tunneling Microscopy Images of Mixed-Ligand-Functionalized Nanoparticles

Francesco Stellacci, Quy Ong Khac, Javier Reguera Gomez

Ligand-protected gold nanoparticles exhibit large local curvatures, features rapidly varying over small scales, and chemical heterogeneity. Their imaging by scanning tunneling microscopy (STM) can, in principle, provide direct information on the architectu ...

Synthesis and Characterization of Janus Gold Nanoparticles

Francesco Stellacci, Randy Patrick Carney, Quy Ong Khac, Javier Reguera Gomez

When gold nanoparticles are coated with binary mixtures of dislike ligand molecules, separation in the ligand shell occurs; if the particles are smaller than a threshold size the separation is solely enthalpy driven leading to the spontaneous formation of ...

Comparative STM studies of mixed ligand monolayers on gold nanoparticles in air and in 1-phenyloctane

Francesco Stellacci, Quy Ong Khac, Javier Reguera Gomez, Shun Zhao

Scanning tunnelling microscopy (STM) studies have found stripe-like domains on gold nanoparticles (NPs) coated with certain binary mixtures of ligand molecules. The majority of these NPs' properties have been investigated for particles in solvents. Yet, mo ...
