Objective To develop a simple microfluidic cell chip
which is enable in adherent cell culture. Methods Arginine-glycine-aspartic acid (RGD) peptide was covalently linked to the microchannel surface of cell chip with biological cross-linker. Through specific identification between RGD and membrane integrin
cells could be adhere to microchannel surface. The functionalization under different concentration of RGD were evaluated. Results RGD peptide was attached on the microchannel surface effectively and uniformly through chemical crosslinking. A549 cells were survival up to 12 h in the microchannel at room temperature without CO
2
because of the good biocompatibility of functional chip. Conclusion Surface modification enables the RGD peptide link to
