MIKROSYSTEME / MICROSYSTEMS
Fig. 3D: Silver nanoparticles were coated with a gold shell in order to tune the plasmon surface resonance
band. Spectra (left), scheme (center), photos of droplets with various gold shell thickness (center right) and
SEM and TEM images of the sample (right).
Fig. 3E: Single particle spectroscopy on immobilized 90 nm silver (left) and 110 nm gold (right) nanoparticles.
The presented spectra were measured on a single particle each.
Fig. 3F: LabOnChip system for droplet-based micro flow-trough PCR. Sample droplets are moved along a
winding micro channel over the different temperature zones according the thermal protocol. The fluidic
module is in thermal contact with a micro system-based heat plate. The thermal distribution as measured
with an infrared camera is shown in the upper right corner. A detailed view of sample droplets inside the
microchannel is given in the lower right corner.
