1. 1. Poly(N-Isopropylacrylamide) Polymer Brush Functionalized Nanostructures as Thermo-Responsive Gating Systems for Protein Transportation

   Författare :Justas Svirelis; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomolecule transportation; Poly N-Isopropylacrylamide ; polymer brushes; fluorescence microscopy; thermo-responsive polymers; surface plasmon resonance;

   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).

   Författare :Justas Svirelis; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomolecule transportation; protein interaction; polymer brushes; quartz crystal microbalance with dissipation monitoring; fluorescence microscopy; Poly N-Isopropylacrylamide ; surface plasmon resonance; poly ethylene glycol ;

   Sammanfattning : Trapping biomolecules in nanosized gaps is of great interest in novel systems for single molecule analysis and membranes, which filter biomolecules. Current platforms are lacking in full functionality to facilitate biomolecule trapping and transport in their native environment and without covalent tethering to surfaces. LÄS MER

5. 4. Adsorption behaviour of bottle-brush and block copolymers at solid-liquid interfaces

   Författare :Geoffrey Olanya; Per M. Claesson; Orlando Rojas; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adsorption; Lubrication; Layer viscoelasticity; Protein repellency; Polymer architecture; Silica; Bottle-brush polymers; Poly ethylene oxide ; PEO; Block copolymer; Poly N-isopropylacrylamide ; QCM-D; AFM; Reflectometry; Surface and colloid chemistry; Yt- och kolloidkemi;

   Sammanfattning : This thesis was spurred on by needs of current scientific and technological developments in the area of surface modification by use of adsorbed polymer layers. The importance of surface properties of polymer layers can be imparted in a broad spectrum of interfacial-related applications like lubrication, colloidal stability, detergency, and protein resistant surfaces, to just mention a few.
