Endowing cell scaffolds with heterogeneity and dynamicity has been recognized as the key element for the next generation of bio-mimic scaffolds for cell culture. In nature, cells in tissues and organs are embedded within the extracellular matrix (ECM), a heterogeneous and dynamic assembly of biochemical and biophysical cues that affect cellular organization and function. Recapitulating these heterogeneity and dynamicity in artificial cell culture systems helps to control the cell behaviors spatiotemporally, which is highly valuable for fundamental cell biology studies, tissue engineering, regenerative medicine and drug development, etc. However, in-situ changing and tracking the mechanical and chemical change of the cell scaffolds are still challenging. To solve this problem, we developed a method to adjust and investigate the physical and chemical properties of the cell scaffold by light. This is achieved by combining normal scaffold materials with dynamic photo-chemistries and self-reporting strategies. By this method we can spatiotemporally control the surface chemistry, stiffness or morphology of a cell scaffold and in-situ monitor their changes in a sealed incubation system (such as microfluidic devices).
