Development of microfluidic channel embedded in a freestanding PDMS membrane
A team of three PhD students at TU Delft achieved the fabrication of a novel and promising device that consists of a microfluidic system embedded in a freestanding PDMS membrane. This device has the potential to be used as universal Organ-on-Chip platform suitable to model an extensive range of organs including Lung-on-Chip, Vessel-on-Chip and Blood-Brain Barrier-on-Chip.
The device can be equipped with the most important features required for an Organ-on-Chip, such as complex microfluidics systems to mimic immune and blood vessels, mechanical stimulation to replicate the forces that tissues experience in vivo, and co-culturing supports to replicate tissue-tissue interface. With the cleanroom compatible micro-fabrication process developed by the team, very large production volume, yield and reproducibility can be achieved, taking Organ-on-Chip beyond its academic applications. The team believes that the device has the potential to improve current in vitro models used during preclinical efficacy and toxicity tests, reducing false negatives and false positives. This invention represents the foundation of the team's venture called Biond LC (living chips)

- Thanks to the support of NanoNextNL, InForMed and hDMT the members of the team had the possibility to start to collaborate.
- The team filed a patent regarding the microfluidic device with the legal and financial support of TU Delft.
- The idea was considered the most promising business case of the 12 StartUp event organized by Yes!Delft (June 2016).
- The team has been awarded a grant by the Nanonext NL valorization program.
- biOnd was one of five startups chosen to participate in the Health Holland Life Sciences@Work venture challange. The winner will be announced at the Dutch Life Sciences Conference in Leiden and will receive 25,0000 euros as well as great exposure at this large life sciences business conference.
