METHOD OF MANUFACTURING MICRONEEDLE FOR TRANSDERMAL DRUG DELIVERY |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing microneedles for transdermal drug delivery for obtaining microneedles for transdermal drug delivery by dry-etching by using a biodegradable material as an article to be processed. <P>SOLUTION: A polylactic acid film 12 is formed on an Si wafer 10 (STEP1). An Al film 14 is formed on the polylactic acid film 12 (STEP2). A processed mask 20 which is patterned by processing the Al film 14 is obtained (STEP5). The microneedle 22 is obtained by processing the polylactic acid film 12 by dry-etching (STEP6). <P>COPYRIGHT: (C)2011,JPO&INPIT |
