Measurement set-up for lab-on-a-chip fluorimetric detection

Fluorimetric detection is widely utilized in analytical applications including pathogen detection, clinical diagnosis and DNA analysis. This method combined with lab-on-a-chip (LOC) technique provides new class of miniature and ultrasensitive bioanalytical tools and therefore new solutions are being widely developed. We present new measurement set-up for lab-on-a-chip fluorimetric detection which consists of silicon-glass LOC microreactor, detection unit with CCD-sensor, semiconductor laser module and dedicated software. Unique image-processing algorithm provides real-time fluorescence signal analysis and databasing.

Wireless passive high-doses radiation sensor

The high dose measurement techniques are of the great interest in nuclear engineering for both, industrial and academic community. Related to these very harsh environment, today sensors solutions are based on external post analysis that not allow real time monitoring. Wireless monitoring of fully chipless passive sensors has been demonstrated for the first time using miniaturized HPD (Hydrogen Pressure Dosimitry) solution. We obtained micrometric silicon membrane deflection for several ten of kGy using 6MeV electron beam.

Wireless hydrogen pressure dosimeter for nuclear high dose monitoring

This communication reports the very first experimental results on an original wireless, chipless and passive (battery-less) sensor for monitoring high doses of nuclear radiation. The micro-sensor combines a miniature hydrogen pressure dosimeter with a passive microwave resonator. The pressure response is derived from Sn-parameter measurement using vacuum and atmospheric pressure conditions. After e-beam irradiation (20kGy) the resonant frequency shift of the resonator ranges between 0.12%/kGy and 0.42%/kGy while the hydrogen pressure inside the cavity varies from 20mbar/kGy to 90mbar/kGy. No significant frequency shift is observed when using sensors during 6 months. These results demonstrate that a good hydrogen hermetic seal was fabricated during the manufacturing process of the constitutive micro-cavity.

Multiscale flow model for simulation of biofluidic mixtures in Lab-Chip devices

Diagnostic Lab-Chip devices contains multiphase and multicomponent biochemical mixtures. For its simulation we propose multiscale flow model, which consist of macro-, meso-and micro-scale submodels. Hybrid Galerkin FEM algorithm was used solving model equations and obtain simulation results.
