A thin-film made of dragline spider silk is produced and fabricated at room temper-
ature using a spin-cast technique; the film’s micromachining, optical and mechanical
characterization is obtained. The mechanical strength of spider silk film is 5 to
10 times greater than the reported strength of hydrogel. Magnetic spider silk thin-film
is also made by photolysis of iron pentacarbonyl mixed with spider silk ...
