MSc. Assignment - Developing an integrated tool for simultaneous thermal, physical and chemical characterization of picoliter volumes of liquid reagents using BMC

What will you be doing?

At the TNO Optomechatronics Department in Delft, the very successful NOMI program (Nano-Opto-Mechatronic Instrumentation) is running. Within this program, fundamental insight into new technologies and innovative concepts are being developed, resulting in the realization of proof of concept demonstrators. This program contains multiple technology lines in the semicon field of use, such as nano-metrology and nano-fabrication to enable the next generation chip manufacturing industry.

Bio-NOMI is a spin-off of this program, in which TNO is developing cross-over technologies between the semicon and biomedical field. Technologies developed for semicon, are being explored, analyzed, re-engineered and realized in order to provide game changing concepts and technologies for biomedical applications. Examples of such technologies are nano-mechanical devices for healthcare applications such as early disease identification and monitoring and medicine efficacy studies for Personal Medicine based on the mechanical properties of tissue, cells or organelles of cells. As an example, it is known that cells infected with cancer are less stiff compared to their healthy counter parts. It is also known that this stiffness changes during the development process. Early detection of mechanical changes and monitoring the change during treatment of the cells and extracellular matrix, might add valuable information needed for effective treatment of the disease.

We are looking for an enthusiastic Master student to help develop an integrated tool for simultaneous thermal, physical and chemical characterization of picoliter volumes of liquid reagents using bimaterial microfluidic cantilever (BMC).This sensors is a combination of MEMS and microfluidics and currently it is being exploited as a very sensitive and selective analytical tool for various applications. It has been successfully demonstrated to perform mass spectrometry of proteins, thermal characterization of polymers, heat capacity measurement of chemicals, antimicrobial resistance, infrared spectrometry, and physical characterization of different solvents. By simultaneously monitoring the static deflection, resonance frequency and quality factory (energy dissipation) of the BMC, it is also possible to perform multiple characterization of picoliter volumes of reagents at the same time. This feature makes it an ideal tool for high throughput application where low sample consumption is of high consideration.

The BMCs are fabricated by Fourien Inc. based in Edmonton, Canada. The goal of this assignment is to develop a low cost optical beam deflection setup to measure the resonance frequency as well as the static deflection of the cantilever. Characterization of noise and signal-to-noise-ratio will be performed to minimize the noise of the instrument. Initially the measurements will be done at atmospheric pressure and room temperature. At a later stage a vacuum chamber would also be incorporated into the setup.

Such a setup would enable the researchers to use the BMC for more precise measurements for fundamental research as well as industry oriented applications. Additionally, this would lead to the development of optical MEMS spectrometer with an ability to simultaneously perform thermal, physical and chemical characterization of extremely small volumes of various reagents.
