Biomolecules can be detected by coupling to the evanescent field of high-Q resonators thus changing the resonance frequency of the later. The aim is to test, model and functionalize arrays of microdisc resonators for massively parallel and highly sensitive detection of biomolecules.

Single-walled carbon nanotubes have either metallic or semiconducting properties depending on their geometric structure (= chiral angle). Semiconducting nanotubes luminesce in the near infrared when individually dispersed in non-quenching environments. This emission can be used as a tracer for mechanical strain as well as chemical change. The thesis project will involve implementation of a confocal microscope imaging system to work in the spectral range 800 - 1400 nm. The imaging system will be used to study nanotube mass transport in various microfluidic setups as well as to study the fluorescence of nanotubes in living.
