A new method for generating a surface density gradient of polymer chains is presented. A substrate-independent polymer deposition technique was used to coat materials with a chemical gradient based on plasma copolymerization of 1,7-octadiene and allylamine ...
Polyelectrolytes composed of an anionic sulfoethyl methacrylate/methacrylate backbone and cationic cyanine dyes counter ions are synthesized. The effective reaction sequence is confirmed by NMR spectroscopy and consists of a thermal radical copolymerizatio ...
Surface-initiated polymerization represents a versatile strategy to modify a diverse range of materials with thin, functional polymer coatings. While in many cases the desired functional groups can be directly incorporated via (co)polymerization of the app ...
The self-assembly of soft matter, such as block copolymers or colloids, allows fine tuning of structure formation on the 10 - 500 nm length scale and therefore enables the design of materials with tunable optical response. We present strategies on how to e ...
Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used to treat acute pain, fever, and inflammation and are being explored in a new indication in cancer. Side effects associated with long-term use of NSAIDs such as gastrointestinal damage and elevat ...
Thin, phenylboronic acid-containing polymer coatings are potentially attractive sensory layers for a range of glucose monitoring systems. This contribution presents the synthesis and properties of glucose-sensitive polymer brushes obtained via surface RAFT ...
Trigger happy: Trigger-responsive chain-shattering polymeric therapeutics (CSPTs) were prepared by condensation polymerization of a UV- or hydrogen peroxide-responsive domain and a drug as co-monomers. Drug release can be started and stopped by starting an ...
A synthetic path to poly(ethylene-co-butylene)-block-poly(ethylene oxide), a substitute for the "KLE" surfactant was developed. For this purpose, mono hydroxyl end-functionalized poly(ethylene-co-butylene) (similar to 3800 g mol(-1)) was modified with a tr ...
Planar solid-supported membranes based on amphiphilic block copolymers represent promising systems for the artificial creation of structural surfaces. Here we introduce a method for engineering functional planar solid-supported membranes through insertion ...
The Chemcatcher passive sampler, which uses Empore (TM) disks as sampling phase, is frequently used to monitor polar organic chemicals in river water and effluents. Uptake kinetics need to be quantified to calculate time-weighted average concentrations fro ...
