LbL coatings enhance physical retention with intestines. a) IVIS images of porcine intestine with plain- and (CHI/ALG)2-probiotics. b) Total radiant efficiency as measured by IVIS of plain-BC (hatched) and (CHI/ALG)2-BC (black). LbL-BC exhibit more rapid growth after 1 h incubation on intestine-mimicking tissues. Non-adherent BC were washed at 1 h and at each timepoint thereafter to ensure signal is exclusively from intestine-bound BC. c) Representative bioluminescent images of plain (top) and LbL (bottom) BC at each timepoint. d) Radiance of LbL- (open squares) and plain-(closed circles) BC as measured by IVIS up to 12 h. Error bars represent standard deviation (n = 3). *denotes statistical difference (P < 0.05) using Student’s t-test between plain and LbL groups. (a) Scale bar = 1.5 cm. (c) Scale bar = 1 cm.
