MIT Hatsopoulos Microfluids Laboratory. The laboratory is a dedicated research center within the Massachusetts Institute of Technology focused on the fundamental science and engineering applications of microscale fluid dynamics. Established through a generous endowment, it supports interdisciplinary work at the intersection of mechanical engineering, chemical engineering, and materials science. The facility is renowned for advancing both theoretical understanding and practical devices in the field of microfluidics.

History and establishment

The laboratory was founded in 1999, made possible by a significant endowment from Nicolaos Hatsopoulos and his family. Hatsopoulos, a distinguished MIT alumnus and co-founder of the American Power Conversion corporation, aimed to create a world-class center for fluid dynamics research at the microscale. The establishment was formally overseen by the MIT Department of Mechanical Engineering under the leadership of then-department head John G. Kassakian. Its creation coincided with a period of rapid growth in biotechnology and nanotechnology, positioning the lab to address emerging scientific challenges. The inaugural research direction was heavily influenced by pioneering work in micro-electro-mechanical systems conducted at institutions like Stanford University and University of California, Berkeley.

Research focus and areas

Primary research thrusts include the development of lab-on-a-chip devices for biomedical diagnostics and high-throughput chemical synthesis. Scientists investigate multiphase flows, electrokinetics, and microscale heat transfer to enable precise control of fluids and particles. A major area involves applying microfluidic principles to energy systems, such as advanced thermal management for electronics and novel fuel cell designs. The lab also pioneers the use of microfluidics in soft robotics and the fabrication of functional materials with tailored properties. Collaborative projects often extend into synthetic biology and point-of-care diagnostics, bridging engineering with the life sciences.

Key facilities and equipment

The laboratory houses a state-of-the-art cleanroom compliant with ISO 14644 standards for fabricating polydimethylsiloxane devices and silicon masters. Core instrumentation includes high-speed micro-particle image velocimetry systems, confocal microscopy setups, and precision syringe pump arrays for flow control. Specialized equipment for photolithography and reactive ion etching supports in-house prototyping of microfluidic chips. Advanced optical diagnostic tools, such as laser-induced fluorescence and digital holographic microscopy, are available for flow visualization and measurement. The facility also maintains computational clusters for running complex computational fluid dynamics simulations using software like COMSOL Multiphysics.

Notable projects and applications

One landmark project developed a portable microfluidic device for rapid detection of HIV and tuberculosis pathogens, field-tested in collaboration with Partners In Health. Researchers have created platforms for screening anticancer drug combinations using arrays of cell culture chambers, work published in journals like *Science* and *Nature Biotechnology*. The lab has contributed to DARPA-funded programs on microfluidic cooling of high-power microprocessors for defense applications. Another significant application is a microfluidic system that mimics the human placenta for pharmaceutical testing, developed with the Wyss Institute for Biologically Inspired Engineering. Work on digital microfluidics for DNA sequencing preparation has also been licensed to several biotechnology startup companies.

People and leadership

The laboratory has been directed since its inception by Professor John G. Kassakian, a noted expert in power electronics and former head of the MIT Department of Mechanical Engineering. Key faculty affiliates have included Gang Chen, known for work on nanoscale heat transfer, and the late Martin Culpepper, an authority on precision engineering. Renowned postdoctoral researchers and visiting scientists, such as Howard A. Stone from Princeton University, have contributed to its intellectual environment. The lab has trained numerous doctoral graduates who have assumed faculty positions at institutions like University of Michigan and California Institute of Technology. Technical staff with expertise in microfabrication and optical engineering provide critical support for experimental research.

Academic and industry impact

The laboratory's research has profoundly influenced the academic field, with its methodologies adopted by groups at Harvard University, ETH Zurich, and University of Tokyo. It has contributed foundational textbooks and chapters in seminal works like the *Springer Handbook of Experimental Fluid Mechanics*. Over fifty patents have been issued from its work, leading to the formation of spin-off companies such as Emulate, Inc. and 10x Genomics. The lab's annual microfluidics workshop attracts participants from global corporations like Pfizer, Intel, and Schlumberger. Its alumni hold key research and development positions in industry leaders including IBM, Thermo Fisher Scientific, and Illumina, Inc., driving innovation in medical devices and analytical instrumentation.
