Microenvironmental mechanical cues influence diverse cellular processes, such as cell migration, cell morphology, and stem cell fate decisions. In our lab, we use mechanical engineering methods and micro/nanofabrication processes to create novel technologies at scales that are biologically relevant and advantageous for studying and controlling cellular functions.
MicroSpring Arrays for Tri-Axial Substrate Control
This project is a collaboration between the M3B Lab and Prof. Shoji Takeuchi’s Biohybrid System Laboratory at the University of Tokyo. For this project, we create arrays of microSprings to facilitate user- control over the “tri-axial” stiffness of discrete, microscale substrate features for cellular applications. In contrast to micropost arrays, which are inherently limited to “bi-axial” stiffness control, microSpring arrays enable researchers to geometrically tune the x-, y-, and z-axis stiffness of each microSpring.
