Functional star polymers as reagents for efficient nucleic acids delivery into HT-1080 cells KU Leuven
Gastro-resistant encapsulation of amorphous solid dispersions containing darunavir by coaxial electrospraying KU Leuven
The relatively simple technique of coaxial electrospraying allows to produce core-shell microparticles with potentially high encapsulation efficiencies. In this study, amorphous solid dispersions of a hydroxypropyl methylcellulose or polyvinlypyrrolidone based polymer matrix containing the active pharmaceutical ingredient darunavir were coated with a gastro-resistant shell polymer that does not dissolve at lower pH present in the stomach, but ...
Synthesis, Characterization and Cytotoxicity of Novel Thermoresponsive Star Copolymers of N,N′-Dimethylaminoethyl Methacrylate and Hydroxyl-Bearing Oligo(Ethylene Glycol) Methacrylate KU Leuven
Novel, nontoxic star copolymers of N,N-dimethylaminoethyl methacrylate (DMAEMA) and hydroxyl-bearing oligo(ethylene glycol) methacrylate (OEGMA-OH) were synthesized via atom transfer radical polymerization (ATRP) using hyperbranched poly(arylene oxindole) as the macroinitiator. Stars with molar masses from 100,000 g/mol to 257,000 g/mol and with various amounts of OEGMA-OH in the arms were prepared. As these polymers can find applications, e.g., ...
Synthesis and post-functionalization of alternate-linked-meta-para-[2n. 1n]thiacyclophanes KU Leuven
In recent decades, considerable research attention has been devoted to new synthetic procedures for thiacyclophanes. Thiacyclophanes are widely used as host molecules for the molecular recognition of organic compounds as well as metals. Herein, we report the selective and high-yielding synthesis of novel alternate-linked-meta-para-thiacyclophanes. These novel thiacyclophanes are selectively synthesized in high-yielding procedures. Furthermore, ...
Synthesis and peptide functionalization of hyperbranched poly(arylene oxindole) towards versatile biomaterials KU Leuven
© 2018 The Royal Society of Chemistry. Hyperbranched polymers (HBPs) are dendritic macromolecules with a three-dimensional globular nanostructure. Due to their unique properties, HBPs are interesting for biomedical applications such as drug/protein delivery and tissue engineering, and functionalized HBPs can be tailored to exhibit specific biological responses. Superelectrophilic arylation of isatin is one strategy to synthesize hydrophobic ...
Saturation reduces in-vitro leakage of monomers from composites KU Leuven
OBJECTIVE: Accurate knowledge of the quantity of released monomers from composites is important. To evaluate the elution of monomers, polymerized composites are typically immersed in an extraction solvent. The objective was to determine whether the volume of extraction solvent and the immersion time influences monomer leachability from dental composite materials. METHODS: Composite disks of two commercial composites, (Filtek Supreme XTE, 3M ESPE ...
