contact@elveflow.com+33(0).184.163.807+1(414)-406-4343 Elveflow is an Elvesys brand, an international microfluidics innovation center with high level researchers dedicated to microfluidics and organ-on-a-chip.
What can you achieve with microfluidics? What are the practical applications of microfluidics to a field of research, and how could microfluidics help your research career?
We asked our own Elveflow research teams for you. Our Microfluidics Careers pages give you a no frills, realistic idea of the wide variety of projects that can benefit from microfluidics.
Lisa Muiznieks PhD is working on protein-based membranes for the Mech-Loc project, which has received funding from the European Union’s Horizon 2020 MSCA-IF under grant agreement No 793749.
There are many interesting things about my project, from the science (often with unpredictable results!), to the engineering challenges, to the design and creativity involved. But one of the most interesting things for me is the power that comes from working as part of a team of researchers with different backgrounds, different training, different perspectives, all working on a common project for a common goal. This brings left-field ideas almost daily, out-of-the-box solutions, constant learning opportunities, and a unified dynamic that is thrilling and addictive.
“This team brings a unified dynamic that is thrilling and addictive.”
I spent many years studying elastic proteins, including elastin that is found in blood vessels, lung and skin and is responsible for the reversible stretch and recoil ability of tissues. My past work with a team at the Hospital for Sick Children in Toronto, Canada, involved using these natural elastic proteins to make thin stretchable materials. Elvesys provided the ideal inter-disciplinary environment to combine elastic materials and microfluidics. The MSCA fellowship opportunity at Elvesys enables me to assemble microfluidic devices with elastic protein-based membranes (made using the same proteins that cells secrete into a network around themselves in the body!) and culture cells inside, with the aim of improving cell models by adding mechanical stimulation.
Conventional cell culture is carried out under largely static conditions. By this we mean that mechanical forces, including stretch, compression and shear stress from fluid flow, that are found in the body and act continuously on cells and tissues, are absent. Microfluidic cell culture chambers shrink the surface that the cells grow on to the order of a millimetre wide and reduce the volume of growth medium (liquid nutrients) required to keep the cells alive. Microfluidic fluid handling allows the perfusion of medium over the cells at a controlled flow rate, allowing study of precise shear stress on cells. It also can be used to apply tension (stretch) to thin membrane surfaces that cells can be grown on, providing a more life-like environment for cells in the laboratory. More physiologically relevant models, in this case, by including mechanical forces, will hopefully result in more realistic studies of disease progression and medicines (drug studies).
“More physiologically relevant models will hopefully result in more realistic studies of disease progression and medicines.”
Mechanical forces provide important stimuli to cells and tissues in the body, directing fundamental processes from the cell level to the whole tissue level. Mechano-sensitive responses include cell growth, movement and cell fate (what cell type they mature into). Already, dynamic culture conditions have shed new light on the spread of cancer (cancer cell migration from a primary tumour site to a secondary location), enhanced models of blood vessel formation, and have been used to investigate the effect of blood flow patterns on clogging in the major arteries (cardiovascular diseases). The stretchable, perfusable lung model offers a more realistic platform to study the effect of drugs on lung cells, the immune response to infections like pneumonia, and the toxicity of tiny particles of pollution in the air.
I am passionate about making dynamic forces and perfusion in cell culture more accessible to non-specialists in microfluidics! I would love to continue to work to bring microfluidic techniques to more researchers in cell and mechanobiology, so that the experts in these fields can advance the state of the art in their research. Together, we are stronger than if we work alone!
Curious about the Mech-Loc project and Lisa’s work on protein-based membranes? She went into its details in her webinar on dynamic cell culture.
We would be glad to join your project to help you to develop a microfluidic system for your specific applications, and share our experience with project submission, innovative product development, and dissemination.

This microfluidic device creates a uniquely accurate method for replicating the actual tumor microenvironment and will be utilized to understand the drug response to the human body.
Soil microorganisms are highly unknown even to this day due to the lack of a proper platform that allows to culture and study them.
The present proposal aims to bridge the gap for high throughput screening of fungicides by designing a novel lab-on-chip device.
