Printing amphotericin B on microneedles using matrix-assisted pulsed laser evaporation





























































           Figure 2. Fourier transform infrared spectra of matrix-assisted pulsed laser evaporation-deposited coatings on glass. Figure (a) shows the
           spectrum for deposition with the AmfB(260) target (amphotericin B 1040 mg/mL + 1% polyvinylpyrrolidone) and Figure (b) shows the
           spectrum for deposition with the AmfB(520) target (amphotericin B 2080 mg/mL + 1% polyvinylpyrrolidone).

           deposition with the AmfB(520) target (amphotericin B   microneedles showed higher surface roughness than the
