16. Optical manipulation and heating of gold nanoparticles near interfaces
Sammanfattning : By focusing laser light to small volumes, its momentum can be used to trap and manipulate objects in the size range from cells down to single atoms. Devices using this effect are called optical tweezers, and have found use in measuring and applying minuscule forces and torques, contributed to deepening our knowledge of molecular motors, unraveling the mechanics of cells and DNA, and better understand statistical mechanics and hydrodynamic interactions at the nanoscale.

Sammanfattning : .... LÄS MER
18. Polypeptide functionalized gold nanoparticles for bioanalytical applications
Sammanfattning : Detection strategies that allow for simple, rapid, cost efficient and sensitive monitoring of proteins and their interactions with biomolecules are of great importance in drug development and diagnostics. This thesis describes the development of bioanalytical applications based on the tunable self-assembly of gold nanoparticles functionalized with a de novo designed polypeptide. LÄS MER
19. Novel methods for improving rapid paper-based protein assays with gold nanoparticle detection
Sammanfattning : This thesis describes methods for improving sensitivity in rapid singleplex and multiplex microarray assays. The assays utilize the optical characteristics of colloidal gold nanoparticles for the colorimetric detection of proteins.Multiplexed detection in sandwich immunoassays is limited by cross-reactivity between different detection antibodies.

20. Nanoparticles based molecular electronic devices with tunable molecular functionalization shell and gas sensing measurements
Sammanfattning : The idea to use molecules as a basic building block in electronic circuits was developed about 50 years ago when a molecular rectifier was developed, but it has been a challenge for this field to make its way to real-world application. Now, due to the advancement in technologies, the properties of single molecules are better understandable and controllable. LÄS MER
