【MOVIE】PDMS microfluidic channels for creating artificial blood vessel models

Customer's Challenge

Customer would like to develop an artificial blood vessel that exhibits contractility similar to real vessels and allows gas permeability.

CSTEC's Proposal

We fabricated a microfluidic channel by machining a flow path into the middle layer of a three-layer PDMS sheet, followed by plasma bonding to achieve molecular binding.
The resulting channel was precisely shaped by processing the outer geometry of the flow path with camera alignment correction, creating an artificial blood vessel structure.
The PDMS structure exhibits flexible elasticity, allowing it to stretch smoothly, and its gas permeability enables efficient fluid transport, making it suitable as an artificial blood vessel model

(A sales representative, Mr. S, came to the factory's cleanroom for the launch of a new product and to ask a difficult process to Mr I.)
Mr. S： "This is quite a challenging lamination...how do you think, Mr. I?"

Mr. I： "This is tough, though… I think it would be better if the customer could relax the standards a little."

Mr. S： "Is there any way to achieve this work? Please!"

(Thanks to Mr.I's efforts, we managed to meet the standards - but the next process will be tough... Let's ask Mr.T's help!)
Mr. S： "I would like to ask your help to overcome this level of precision..."

Mr. T： "That is really pushing it, however, I will do my best!"

Thanks to the factory's hard work, we were able to deliver a product that satisfied the customer.

At CSTEC, we have a culture of never giving up on difficult processing challenges. Before saying "No", we always try to take on the challenge. So please feel free to ask us!
