Fig. 7From: Layer-by-layer assembled polymeric thin films as prospective drug delivery carriers: design and applicationsa Schematic illustration of the preparation procedure of bFGF-incorporated LbL films on magnetic nanoparticles. b Loading amount of bFGF onto three kinds of films represented as G1, G2 and G3 in the figure. The G films (growth factor films) included only bFGF and heparin for G1; bFGF, PLL and heparin for G2 and GO; and bFGF and heparin for G3. (Reprinted with permission from Ref. [59].
