Imaging Radial Distribution Functions of Complex Particles by Relayed Dynamic Nuclear Polarization

David Lyndon Emsley, Arthur César Pinon, Pierrick Berruyer

The physical properties of many modern multi-component materials are determined by their internal microstructure. Tools capable of characterizing complex nanoscale architectures in composite materials are, therefore, essential to design materials with targ ...

Revealing the Formation Dynamics of Janus Polymer Particles: Insights from Experiments and Molecular Dynamics

Philip Robin Loche

Seeded emulsion polymerization is one of the best-known methods for preparing polymer particles with a controlled size, composition, and shape. It first requires the preparation of seed particles, which are then swollen with additional monomer (the same as ...

Plasmon-induced near-infrared fluorescence enhancement of single-walled carbon nanotubes

Ardemis Anoush Boghossian, Giulia Tagliabue, Sayyed Hashem Sajjadi, Alessandra Antonucci, Shang-Jung Wu, Theodoros Tsoulos, Amirmostafa Amirjani

Single-walled carbon nanotubes (SWCNTs) emit near-infrared (NIR) fluorescence that is ideal for optical sensing. However, the low quantum yields diminish the sensor’s signal-to-noise ratio and limits the penetration depths for in vivo measurements. In this ...

Ion-bridges and lipids drive aggregation of same-charge nanoparticles on lipid membranes

Francesco Stellacci, Zekiye Pelin Güven, Giulia Rossi

The control of the aggregation of biomedical nanoparticles (NP) in physiological conditions is crucial as clustering may change completely the way they interact with the biological environment. Here we show that Au nanoparticles, functionalized by an anion ...

Adsorption of progesterone onto microplastics and its desorption in simulated gastric and intestinal fluids

Florian Frédéric Vincent Breider, Dominique Grandjean, Thibault Béranger Masset, Cécilia Laetitia Carla Siri, Yang Liu

The sorption of Hydrophobic Organic Compound (HOC) onto microplastics is relatively well reported in the literature, while their desorption remains poorly investigated, and especially in biological ﬂuids. The present study investigated the sorption and des ...

Insight into the Growth of Anisotropic CdSe Nanocrystals: Attachment of Intrinsically Different Building Blocks

Martinus Gijs, Virendra Kumar Parashar, Xiaopeng Huang

An in-depth understanding of the growth mechanism of nanocrystals (NCs) is of great significance for shape control of colloidal semiconductor nanostructures. In this study, we elucidate the formation mechanism of anisotropic CdSe NCs by systematically inve ...
