Protein-resistant monolayers prepared by hydrosilylation of α-oligo(ethylene glycol)-ω-alkenes on hydrogen-terminated silicon (111) surfaces

Atomically flat, homogeneous, and protein-resistant monolayers can be readily prepared on H–Si(111) surfaces by photo-induced hydrosilylation of α-oligo(ethylene glycol)-ω-alkenes.

Anaerobic conditions to reduce oxidation of proteins and to accelerate the copper-catalyzed “Click” reaction with a water-soluble bis(triazole) ligand

Oxidation of protein (bovine albumin serum) by air still occurred under the copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction conditions even in the presence of a Cu(I)-stabilizing tris(triazole) ligand. Anaerobic conditions not only avoided the oxidation of the protein, but also greatly accelerated the CuAAC reaction using a water-soluble bis(triazole) Cu(I) ligand.

Formation of robust mesoscopic ring structures by self-assembly of SiCl3-terminated dendrimers

Robust sub-micrometer ring structures are easily prepared using SiCl3-terminated dendrimers.
