Journal ArticleDOI
Covalent surface modification of oxide surfaces.
TL;DR: This Review presents one approach to obtain robust surface modifications of the surface of oxides, namely the covalent attachment of monolayers.
Journal ArticleDOI
Role of surface charge and oxidative stress in cytotoxicity of organic monolayer-coated silicon nanoparticles towards macrophage NR8383 cells
Sourav Bhattacharjee,Laura H.J. de Haan,Nynke M. Evers,Xue Jiang,Antonius T. M. Marcelis,Han Zuilhof,Ivonne M.C.M. Rietjens,Gerrit M. Alink +7 more
TL;DR: Investigating the role of surface charge, oxidative stress and possible involvement of mitochondria in the production of intracellular reactive oxygen species (ROS) upon exposure of rat macrophage NR8383 cells to silicon nanoparticles found surface charge of Si-core nanoparticles plays an important role in determining their cytotoxicity.
Journal ArticleDOI
Bilayer vesicles of amphiphilic cyclodextrins: host membranes that recognize guest molecules.
Patrick Falvey,Choon Woo Lim,Raphael Darcy,Tobias Revermann,Uwe Karst,Marcel Giesbers,Antonius T. M. Marcelis,Adina N. Lazar,Anthony W. Coleman,David N. Reinhoudt,Bart Jan Ravoo +10 more
TL;DR: It was found that in spite of the presence of oligo(ethylene glycol) substituents, the beta-cyclodextrin vesicles retain their characteristic affinity for adamantane carboxylate, and can function as host bilayer membranes that recognize small guest molecules by specific noncovalent interaction.
Journal ArticleDOI
Cytotoxicity of surface-functionalized silicon and germanium nanoparticles: the dominant role of surface charges
Sourav Bhattacharjee,Ivonne M.C.M. Rietjens,Mani P. Singh,Tonya M. Atkins,Tapas K. Purkait,Zejing Xu,Sarah Regli,Amber M. Shukaliak,Rhett J. Clark,Brian S. Mitchell,Gerrit M. Alink,Antonius T. M. Marcelis,Mark J. Fink,Jonathan G. C. Veinot,Susan M. Kauzlarich,Han Zuilhof +15 more
TL;DR: The results explain the toxicity of Si NPs/Ge NPs largely by their surface characteristics, provide insight into the mode of action underlying the observed cytotoxicity, and give directions on synthesizing biocompatible Si and Ge NPs, as this is crucial for bioimaging and other applications in for example the field of medicine.
Journal ArticleDOI
A Twist‐Bend Nematic Phase Driven by Hydrogen Bonding
Suzanne M. Jansze,Alfonso Martinez-Felipe,John Storey,Antonius T. M. Marcelis,Corrie T. Imrie +4 more
TL;DR: Temperature-dependent FTIR spectroscopy reveals differences in hydrogen bonding between the two nematic phases shown by CB6OBA which suggest that the open hydrogen-bonded complexes may play an important role in stabilizing the helical arrangement found in the twist-bend nematic phase.
