Various sulfated vinyl saccharides have also been proposed as heparin-mimicking polymers, for the binding of growth factors and to prevent amyloid b aggregation . Another strategy proposed for the capture of heparin-binding growth factors was based on the design of copolymers featuring styrene sulfonate residues. This enabled the design of copolymers allowing the stabilisation of fibroblast growth factor 2 and promoted binding of the corresponding receptor (through a poly(vinyl sulfonate) block) . Similarly, nanopatterns of poly(styrene sulfonate) and RGD peptides allowed the capture of basic fibroblast growth factor and the regulation of cell adhesion .
