Dilution versus fractionation: Separation technologies hyphenated with spICP-MS for characterizing metallic nanoparticles in aerosols

Jian Wang, Christian Ludwig, Andrea Testino, Tianyu Cen

The presence of metal salts has become one of the major limitations for measuring metallic nanoparticles (NPs) in single particle inductively coupled plasma mass spectrometry (spICP-MS). Their presence generates a background signal in spICP-MS that can be ...

Optical manipulation of plasmonic nanoparticles: Applications in surface chemistry and nano-optics

Jeonghyeon Kim

Optical tweezers are devices that can manipulate nano- and microparticles using a laser. The principle of optical tweezers is to apply a force to an object using the momentum of light. This force is very small, but it is sufficient to move things in the mi ...

Characterizing crystalline defects in single nanoparticles from angular correlations of single-shot diffracted X-rays

Christoph Bostedt, Alessandro Colombo, Giorgio Rossi

Characterizing and controlling the uniformity of nanoparticles is crucial for their application in science and technology because crystalline defects in the nanoparticles strongly affect their unique properties. Recently, ultra-short and ultra-bright X-ray ...

Multidimensional Characterization of Mixed Ligand Nanoparticles Using Small Angle Neutron Scattering

Francesco Stellacci, Stefan Guldin, Ye Yang, Zhi Luo

The properties of ligand protected gold nanoparticles are determined by the synergistic interplay of their structural components, including the metal core, the ligand shell, and the solvation layer. However, the simultaneous characterization of all these c ...

Synthesis and Characterization of Amphiphilic Gold Nanoparticles

Francesco Stellacci, Paulo Henrique Jacob Silva, Matteo Gasbarri, Zhi Luo, Zekiye Pelin Güven, Urszula Beata Cendrowska, Samuel Thomas Jones

Gold nanoparticles covered with a mixture of 1-octanethiol (OT) and 11-mercapto-1-undecane sulfonic acid (MUS) have been extensively studied because of their interactions with cell membranes, lipid bilayers, and viruses. The hydrophilic ligands make these ...
