Polymeric substrates, release mechanism

Even through Zeoli s proposal does not apply to rubber septa, one cannot automatically assume all polymeric substrates will release by a first order mechanism. In pol3nmers of greater viscosity or larger volume to surface area ratios, diffusion within the polymeric matrix might become the rate determining step or at least become comparable in magnitude to the evaporation step. [Pg.109]

Gene delivery from polymeric biomaterials forming the scaffold can be due to two general mechanisms polymeric release or substrate-mediated delivery (Figure 15.4). [Pg.414]
