data using the method of Makievski et al. (1997). Appropriate techniques for
measuring dynamic surface tension include the pendant bubble and droplet
methods that are critiqued by Li et al. (2010). Figure2.2 shows dynamic sur-
face tension data for the protein bovine serum albumin measured using the
pendant bubble method, and Figure2.3 extrapolates the same data to innite
