Table 2.

Mean hydrated mass of BSM and total hydrated mass of WPI and PPI (heated or non-heated) after the adsorption onto gold or PDMS surface, latter in presence or absence of mucin coating. Samples with the same superscript letter do not differ significantly (p > 0.05) according to Tukey's test.
