Fig. 1From: Atomic layer deposition coating of carbon nanotubes with zinc oxide causes acute phase immune responses in human monocytes in vitro and in mice after pulmonary exposureAtomic layer deposition (ALD) of ZnO on MWCNT. a Schematic of ALD on a generic surface. Reactants are introduced sequentially to build one self-limiting monolayer of material at a time. b ZnO thickness and material weight gain increase linearly with the number of ALD cycles. c TEM micrographs of MWCNT, uncoated and coated, show tube length decreases following sonication. Higher magnification images show conformal coatingBack to article page
