Added value Eindhoven University of Technology for hDMT
• The expertise at TU/e contributed to hDMT enables development of the technical platforms
needed to create a micro-environment in which complex tissue structures can be grown,
manipulated and studied, mimicking in vivo processes.
• Materials are essential in organ-on-a-chip devices, since they define the direct microenvironment
of the biological tissue. The chemical, mechanical, and electronic properties of the material
can drive biological processes such as cell differentiation and tissue formation. The materials
expertise contribute the necessary material knowledge and expertise to synthesize, process,
and integrate materials.
• Organ-on-chip are integrated devices – different components made of different materials must
be combined to create a functioning device. We make integrated devices such as microfluidic
devices with microactuators based on responsive materials that can apply deformation,
forces, or fluid flow, surface topography that can steer fluidic or biological processes, organic
electronics for applying electrical stimuli or reading out electrical signals, devices allowing for
magnetic actuation of particles for diagnostics, etc.
• Theoretical and numerical models can be essential for an efficient and effective design of
organ on chip applications, and may help to guide and understand cell and tissue behavior in
the chip environment.
Added value hDMT for Eindhoven University of Technology
• Collaboration with hDMT partmers, with complementary expertise (medical / clinical expertise,
cell-biology, and complementary technology), all needed to develop organ-on-a-chip, provides
opportunities for TU/e to contribute to exciting and highly relevant applications in this area.
• hDMT provides the opportunity to leverage our developed materials and technologies.
• hDMT provides TU/e with novel research questions, which will certainly drive new developments
in materials, technologies, manufacturing approaches, devices, and models.
• Availability of infrastructure at hDMT partners provides TU/e new opportunities (for
characterization and processing).
Expertise and facilities:
The expertise at TU/e contributed to hDMT enables development of the technical platforms needed
to create a micro-environment in which complex tissue structures can be grown, manipulated and
studied, mimicking in vivo processes. This expertise can be divided into 3 classes: materials,
device integration, and modelling.
