Vertical Flow Test of Foams 1, 2, and 4 on porcine chest walls ex vivo at 37 °C. The insets show the original areas of foam delivery, applied horizontally, prior to tissue being hung vertically. (a) Foam 1, created from TF-15, flowed off the tissue leaving residual solution behind. (b) Foam 2, created from TF-20, flowed down the tissue leaving gelled foam coating the tissue. An image of the original area of administration was not available but was similar to the inset of (a). (c) Foam 4, created from TF-25, mostly remained in the original location of delivery with the exception of a few isolated drips
