Scheme 1 showed the structure of egg membrane contained AgNPs
in the experiment. First, the egg membrane was taken from fresh egg
shell and cleaned by DDW. Then the egg membrane was soaked in the
colloidal AgNPs which were prepared in Section 2.2 for 1 h and dried
for 3 h in the oven at 30 °C. Dried egg membrane was cut into
25.0 mm × 19.0 mm rectangular shape and put in the middle of the
tape neatly. Next, the tape was treated in the ultrasonic cleaning instrument
for 10 min. The egg membrane bandage contained AgNPs was
finally obtained.
