The percentages of
AgNPs grown on silk that are converted into Ag+ can be calculated
based on the release profiles and the TGA data. 7.5%, 5.8%, 6.5% and
8.4% silk surface-immobilized AgNPs are released into the PBS
solutions in the form of Ag+ for the samples with 2, 4, 6 and 8 bilayers
of polyelectrolytes, respectively.
