In vitro biological test results for several cellulose-based aerogels: (1) Representative confocal images of the expression of cytoskeleton marker actin (in green) and nucleus marker 4′,6-diamidino-2-phenylindole (DAPI) (in blue) for composite aerogels of NFC and mesoporous bioactive glass (MBG) incubated with 3T3 fibroblast cells (1a), and cell proliferation profiles measured after 2 days and 6 days of incubation, * p < 0.1; ** p < 0.01; *** p < 0.001 (1b).

(2) FE-SEM images of cells seeded on pristine bacterial cellulose (2a,2b) and bacterial cellulose/AgNPs/polyaniline (PANI): bacterial cellulose/PANI aerogel in 0.25 M HCl (BP-0.25) (2c,2d), bacterial cellulose/AgNPs aerogel (BA3) (2e, 2f), bacterial cellulose/AgNPs/PANI aerogels in 0.01 M HCl (BPA3-0.01) (2g,2h), and in 0.25 M HCl (BPA3-0.25) (2i,2j), respectively, after 1 day (2a,2c,2e,2g,2i) and 7 days (2b,2d,2f,2h,2j); antibacterial activities of composite aerogels against Staphylococcus aureus (S. aureus) (2l) and against Escherichia coli (E. coli) (2k), respectively.
