5. 4. Novel Functionalized Nanopores for Plasmonic Sensing

   Författare :Bita Malekian; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; extinction spectra; nanopores; proteins; nanocaves; nanowells; surface plasmon resonance; nuclear pore complex; colloidal lithography; nanoplasmonic sensor; label-free sensing; electron beam lithography; plasmonic nanostructures;

   Sammanfattning : Nanoplasmonic sensors offer a label-free platform for real-time monitoring of biomolecular interactions by tracking changes in refractive index through optical spectroscopy. However, other surface sensitive techniques such as conventional surface plasmon resonance offer similar capabilities with equal or even better resolution in terms of surface coverage. LÄS MER

7. 5. Interpolymer complexation of a polymer brush

   Författare :John Andersson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; functional materials; macromolecular gating; Interpolymer complex; nanopores; polymer brush; pH responsive;

   Sammanfattning : Controllable macromolecular gating between nanoscopic compartments is of high interest for single molecule studies of biological macromolecules. By definition, a good macromolecular gate should completely stop biomolecules, such as proteins, from crossing between compartments in its closed state while letting them pass in its open state.
