Fig. 6From: Laminar flow assisted anisotropic bacteria absorption for chemotaxis delivery of bacteria-attached microparticleSEM images of microparticles (50 um × 50 um). The bacteria were selectively absorbed at (a) front/left surface and (b) top/right surface. Inset (i)–(iv) showed the magnified image of various surfaces that confirmed the anisotropic absorptionBack to article page
