High-resolution X-ray micrographs of bare Au and MUA-Au NPs in the C. elegans intestine. (a) 2D high-resolution X-ray micrographs in the absence of Au NPs. (b) 2D high-resolution X-ray micrographs of bare Au NPs. (c) 2D high-resolution X-ray micrographs with an increasing MUA: Au ratio of 1:2. (d) 2D high-resolution X-ray micrographs with an increasing MUA: Au ratio of 1:1. (e) 2D high-resolution X-ray micrographs with an increasing MUA: Au ratio of 3:1. (f) 3D reconstruction of the micrographs in (b). After incubating worms with bare Au NPs for 12 hours, aggregation was found in the worm intestines, demonstrating that bare Au NPs can be taken up by C. elegans. Scale bars: 100 µm.
