3D Printed Franz cells - update on optimization of manufacture and evaluation

The evaluation of permeation profiles from cosmetic formulations is considered to be a crucial component in both the development and quality assurance of any new product [1, 2]. Data gathered from such studies allow researchers to assess the viability of delivering different materials to and through biological membranes. To date, laboratory in vitro permeation processes require the use of modified Franz type diffusion cells, conventionally fabricated from glass, which are available in different formats that can be customised to experimental requirements [3]
