Fig. 4From: Biological applications of the NanoSuit for electron imaging and X-microanalysis of insulating specimensCherry blossom petals. A–C Schematic drawings of a conventional fixation protocol, a NanoSuit method with beam irradiation and no fixation, and a control with neither beam irradiation nor fixation. D, E, and J Photograph, SEM image, and TEM image of the conventionally-processed petal. Arrow = surface material. F, G, and K Photograph, SEM image, and TEM image of the NanoSuit-formed petal. Arrowhead = polymerized surface layer. H, I, and L Photograph, SEM image, and TEM image of the control petal. Bars = 2 mm (D, F, and H), 10 μm (E, G, and I), 300 nm (J, K, and L).
