MSc thesis project proposal

[2024] 3D Printed Bioelectronics for Regenerative Medicine

Background: The future of 3D printing in healthcare is incredibly promising, with ongoing research into bioprinting tissues and organs. This could potentially lead to on-demand production of living body tissues, blood vessels, and even whole organs. Recently, it has become practicable to 3D print organic electronic materials[1] to construct bioelectronic devices to monitor and stimulate biological activity. This creates exciting new opportunities for bioelectronic research, particularly for stem cell engineering.

Aim: This project targets to the development of highly biomimetic, and electrically active 3D printed bioelectronic devices to be used for regenerative medicine. Functional inks will be developed by combining the organic electronic materials, i.e. PEDOT:PSS,[2] with biomaterials that are found in our body, i.e. collagen. These functional inks will be 3D printed with a commercially available 3D printer in electrode and transistor configurations[3] and be used to develop functional tissue with stem cells.  

The student will have access to the Bioelectronics section and cleanroom (EKL) facilities at TU Delft to carry out the work.
