Abstract :
We report a novel chemical and biological sensing metrology by combining both frequency-domain terahertz and microfluidic techniques through the quasi-optical approach. Using this sensing platform, a variety of chemicals have been examined over the frequency range of 0.57-0.63 THz. In addition, real-time monitoring and THz mapping of two-stream mixtures and diffusions in a microfluidic device are also successfully demonstrated. This strategy represents a versatile approach that may enable a wide range of chemical and biological applications.
