(A) Schematic procedure for the fabrication of the nanostructured film. (B) Scanning electron microscopy (SEM) image of HA-CTSNF substrate. (C) Grafting of biotinylated epithelial-cell adhesion-molecule antibody (anti-EpCAM) onto HA-CTSNF substrate. The cell capture yields of the HA-CTSNF substrate with (D) different surface roughness of nanostructured film ranging from 20 to 280 nm and (E) at different incubation time (with incubation time of 15, 30, 45, 60 and 90 min). (F) Capture efficiencies of four different cell lines at the optimal cell capture conditions. (G) Comparison of capture efficiency of new version of HA-CTSNF with two different controls: (i) HA-CTSNF, (ii) TiO2 nanoparticles. Error bars show standard deviations (n = 3).
