Abstract

A poly-lactic acid (PLA) microneedle array of maximum aspect ratio 18 was fabricated by Drawing lithography. In the fabrication method proposed in this study, melted PLA is stretched twice. Various aspect ratios can be set according to the length of the first stretching. The final aspect ratio and shape of microneedle can be controlled by the second stretching. Finally, puncture ability was evaluated using artificial skin and porcine skin.
