Microfluidic technology has been extensively used for efficient manipulation of fluids in a microscale for energy, biomedical research, environmental monitoring, and analytical chemistry. The control of flow in microchannels is crucial in many fluid mechanic applications, such as molecular diagnostics, cell sorting and separation, fluid mixing, and cell adhesion and culture. The flow rate may need to be accurately quantified as it may lead to size variation in the products.
Also, having access to a miniaturized system that can perform selective manipulation of biophysical and biochemical properties of liquids in microchannels while enabling non-contact sensing exceeding the available market sensitivity even for non-transparent mediums is an urgent need of many lab-on-a-chip platforms. We have enabled proper integration of microfluidics with long-lasting and sensitive microwaves to bring both worlds of sensitivity and selectivity into one single chip.
The researchers at the University of Calgary have developed a non-contact and real-time sensing apparatus and method for measuring the physical and chemical characteristics of fluid within microfluidic channels.
