1. Poly(N-Isopropylacrylamide) Polymer Brush Functionalized Nanostructures as Thermo-Responsive Gating Systems for Protein Transportation
Sammanfattning : Controlling molecule translocation through nanosized gaps is of great interest in novel systems for single molecule analysis and biomolecular membranes. The molecular gating property of thermo-responsive end-grafted poly(N-isopropylacrylamide) (PNIPAM) polymer brushes on well-shaped gold-silica nanostructures is intended to be investigated for controlled protein transportation via extinction spectroscopy and fluorescence microscopy methods below and above PNIPAM lower critical solution temperature (LCST; 32 °C in water).

2. Specific Precipitation of Biomolecules Using Synthetic Polymers
Sammanfattning : Purification is a very important stage in biotechnological processes. The traditionally used precipitation techniques are generally nonspecific and thus one or more chromatographic steps are normally required. There is thus a need for new approaches to improve existing techniques. LÄS MER
3. Exploring Amphiphilic PEGMA-Based Architectures as Nanoparticles for Drug Delivery
Sammanfattning : Within the last decades, the stated potential of polymer constructs as drug delivery systems have challenged researchers to develop sophisticated polymers with tunable properties. The versatility of polymers makes them highly attractive to tailor nanoparticles (NPs) which fulfill the demands of effective drug delivery systems (DDS). LÄS MER
4. Inorganic and organic polymer-grafted nanoparticles : their nanocomposites and characterization
Sammanfattning : Nanocomposites (NCs) have been widely studied in the past decades due to the promising properties that nanoparticles (NPs) offer to a polymer matrix, such as increased thermal stability and non-linear electrical resistivity. It has also been shown that the interphase between the two components is the key to achieving the desired improvements. LÄS MER
5. Tailoring Surface Properties of Bio-Fibers via Atom Transfer Radical Polymerization
Sammanfattning : The potential use of renewable, bio-based polymers in high-technological applications has attracted great interest due to increased environmental concern. Cellulose is the most abundant biopolymer resource in the world, and it has great potential to be modified to suit new application areas. LÄS MER
