Optical micrographs showing the insertion sites in surgically discarded human abdominal skin for (A) an uncoated polyglycolic acid microneedle array, (B) a matrix-assisted pulsed laser evaporation-coated microneedle array from deposition with the AmfB(260) target (amphotericin B 1040 mg/mL + 1% polyvinylpyrrolidone), and (C) a matrix-assisted pulsed laser evaporation-coated microneedle array from deposition with the AmfB(520) target (amphotericin B 2080 mg/mL + 1% polyvinylpyrrolidone). The location of microneedle insertion was identified using methylene blue dye.
