Diagnostics and biosensing using nanostructures and discs
The optics and mechanics from a DVD player can be used to realize compact and sensitive sensor systems. By rotating a polymer disc with integrated microfluidic channels it is possible to manipulate liquid samples such as blood – performing crucial operations like separation, valving and mixing. We integrate sensor elements such as cantilevers, nanoparticles, resonating strings and surface enhanced Raman scattering (SERS) substrates with centrifugal microfluidics. The sensors are read out by a DVD pick-up head which can perform transmission/absorption measurements and which can detect nm deflections. Also, electrodes are integrated on a disc platform, facilitating electrochemical measurements. Examples of applications include rapid diagnostics, prognostics and studies of thermal properties and degradation of polymers.
