Skin histology of microwave modified skin for transdermal drug delivery / Muhammmad Najhan Md Bohari

The effect of microwave on rat skin histology for the application in transdermal drug delivery was examined. Four types of pectin (P) films and gels were prepared by dissolving the pectin powder with or without oleic acid (OA) in deionised water under continuous stirring at 25 ± 1°C for 15 h. The sk...
