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 ...

Rotating disk diluter hyphenated with single particle ICP-MS as an online dilution and sampling platform for metallic nanoparticles characterization in ambient aerosol

Christian Ludwig, Andrea Testino, Tianyu Cen

The application of single particle inductively coupled plasma mass spectrometry (spICP-MS) for online metallic nanoparticles (NPs) characterization in ambient aerosol remains a challenge. In this study, a hyphenated setup consisting of a rotating disk dilu ...

Inhalation of climbing shoe particles is highly relevant for the human exposure to rubber-derived chemicals in indoor facilities

Florian Frédéric Vincent Breider, Thibault Béranger Masset

There is increasing research focused on rubber-derived chemicals (RDCs), predominantly originating from tire and road wear particles. Other consumer products also contain RDCs, but the overall human exposure to these compounds is unknown. This study invest ...

Surface engineering of T cells with polymer nanoparticles to enhance drug delivery to the brain

Markus Schuster

Firstly, this thesis presents the in vivo evaluation of a previously developed model system that utilizes CD4+ TE/M cells decorated with up to 100 polystyrene based nanoparticles per cell by maleimide thiol conjugation. These nanoparticle T-cell conjugates ...

Re-entry survival analysis and ground risk assessment of space debris considering by-products generation

Pénélope Leyland, Stefano Mischler, Seong-Hyeon Park

Space debris that re-enter the Earth's atmosphere can be partially or fully ablated along the trajectory path after hitting the atmosphere layers, once these become denser (approximately below 82 km). This paper combines re-entry survival analysis to by-pr ...

On the effect of ligand shell heterogeneity on nanoparticle/protein binding thermodynamics

Francesco Stellacci, Ahmet Bekdemir, Suiyang Liao

Nonspecific protein adhesion to nanoparticle (NP) has been proven to have important implications in nanomedicine. However, there are only a few examples of careful studies relating protein binding thermodynamics to NP physicochemical features. In particula ...

Mass spectrometry and Monte Carlo method mapping of nanoparticle ligand shell morphology

Francesco Stellacci, Zhi Luo, Yanfei Zhao, Jing Hou, Yue Wang

Janus, patchy, stripe-like, or random arrangements of molecules within the ligand shell of nanoparticles affect many properties. Among all existing ligand shell morphology characterization methods, the one based on mass spectroscopy is arguably the simples ...

Advanced characterization methods for self-assembled organization on nanoparticles

Zhi Luo

The complex organizations of amino acid residues on protein surfaces give rise to a wide space of functions for proteins. Great efforts are devoted in biology to understand such structure-property relationships. Many advanced characterization techniques ha ...

Beyond Unpredictability: The Importance of Reproducibility in Understanding the Protein Corona of Nanoparticles

Heinrich Hofmann, Diego Chiappe, Lionel André Maurizi, Sandra Caroline Galmarini, Nadia Rachel Von Moos, Noëlie Cayla

While it is well established that the surface of a nanoparticle plays a pivotal role for the protein corona, the vast number of proteins present in biological media render general conclusions about affinities between nanoparticle surfaces and proteins nont ...
