Microwave Lab-on-Chip
Why lab-on-chip?
Lab-on-chip (LoC), also referred to as micro-total-analysis systems (μ-TAS), is an emerging technology driver in More Than Moore era when scaling is approaching the fundamental limits while the momentum of silicon technologies and the available computing power provide a versatile and dominant technology platform.
The history and development of computer technology indicate the great potential and exciting future of lab-on-chip.
Why microwave?
Current electronic LoC efforts, such as impedance spectroscopy, nano pipettes and silicon nanowire/carbon nanotube field effect transistors (FETs), operate at DC and low frequencies, where physiological liquids often impose application limits.
High frequency techniques are promising to address such limitations and provide a few desirable characteristics, including non-invasiveness, high information contents and high sensitivity. The high information contents are promising to yield microwave specificity for label-free differentiation of materials.
At the same time, high frequency techniques are the backbone and the frontier of high speed circuit design and wireless communication development.
