Welcome to Hirai Lab.

Creating Micro/Nano Technology to Shape the Future

Our core technologies are materials, fabrication and packaging, as well as applications of the fabricated micro/nanostructures, devices and micro/nanosystems.

Alone we go faster, Together we go further!

Photo: Body on a Chip (BoC)-BoC technology uses microfluidic systems and advanced tissue engineering techniques to create a system that mimics the complexity and interactions of different human organs and tissues. BoC has the potential to revolutionize the field of medicine by providing more accurate and efficient methods for drug development, disease modeling and personalized medicine.

Two-organ chip to answer fatty liver questions

A new chip that holds different cell types in tiny, interconnected chambers could allow scientists to better understand the physiological and disease interactions between organs. The integrated-gut-liver-on-a-chip (iGLC) platform was designed by scientists at Kyoto University, to improve understanding of non-alcoholic fatty liver disease (NAFLD). The researchers, together with colleagues in Japan, published their findings in the journal Communications Biology. (More)

Research highlight

Enhancing realism of gut-liver axis model: Organ-on-chip device allows separate flows for gut and liver cells, producing a more realistic model of gut and liver interactions in humans that could be used to study related diseases and their treatments.
