Cooling of an integrated magnetic sensor by using microfluidics channels
This interdisciplinary European project “Biological diagnostic tools using Microsystems and supersensitive magnetic detection” focuses on development of new instrumentation for immunoassays and high throughput screening aiming for unprecedented performance in terms of sensitivity, speed and sample handling, by combining:
(i) bio-functionalized magnetic nanoparticles (ca. 100 nm);
(ii) high sensitivity magnetic detection (SQUIDs);
(iii) microfabricated Lab-on-Chip.
SQUIDs (Superconducting QUantum Interference Devices) are the most sensitive magnetic field detectors known. Such a high sensitivity is achieved by means of superconductivity, which requires cooling below the material critical temperature Tc (around 9 K for low-Tc Niobium and 80 K for high-Tc materials).
Goal of the project:
Investigate the feasibility to miniaturize the cooling system by using microchannels directly under the SQUID sensor.
The results should be presented in a written report and in a seminar.
The research at the Department of Microtechnology and Nanoscience, MC2, covers a wide range of disciplines in microtechnology and nanoscience. Large efforts, experimental as well as theoretical, are directed at materials, devices and subsystems for future micro/nanoelectronics in the fields of microwave electronics, quantum devices, photonics, micro- and nanosystems, superconducting devices and circuits and molecular electronics just to mention a few.
The research at Solid State Electronics Laboratory focuses on device structures and components based on silicon and III-V materials, circuits and microsystems and circuit design in superconducting electronics
