Microengineering - Production of High Aspect Ratio Microstructures

SU8 Materia

Techniques commonly used by the microelectronics industry have been adapted to produce structures for use in tissue engineering. We have investigated the suitability of a number of engineering techniques for use in producing 3D scaffolds. Each technique has unique advantages such as edge definition and resolution (for the microengineered structures), flexibility and choice of material (soft lithography), and the structured 3D capabilities (of the rapid prototyping systems).

In conjunction with the development of new biomimetic polymers, we are intending to integrate these technologies such that we can produce tissue engineering scaffolds which more accurately reflect the complex nature of the biological system into which it is being placed. This should allow us a better understanding of the wound healing process when tissue damage occurs.
