Thus, ecological effects should also be concerned before the
application of antimicrobial silk with different AgNPs loading
amount. Besides the secretion of Ag+
, the leaching of AgNPs into
the micro environment is another critical issue that needs to be
considered for the maintenance of the AgNPs-coated silk. Since
the characterization of AgNPs leached from the silk is a great challenge,
further investigations are still carrying out in our laboratory
to explore the stability of the AgNPs embedded in silk surface immobilized
polymers.
