Abstract

The paper presents the recent results of the spreading and traction of human osteosarcoma cells on soft polydimethylsiloxane (PDMS) microgrooved surfaces. The results show that the cell tractions resulted in significant deformation of the microgrooves. The tractions were calculated, and found to be in good agreement with the results from other studies. The results suggest that the cell spreading-induced soft substrate deformation needs to be considered in the design of implantable bioMEMS structures.
