Single cell capture onto Si 1D structures. (a) NWs length-dependent triggered improvement of prostate cancer cell line (PC-3) capture. Fr-S stands for frosted slide, and Fr-S-SNW stands for SiO₂ NWs-decorated slides at different NW lengths (0.5–2.5 µm). (b) Corresponding SEM images of the captured cells. (c) Immunofluorescence images staining (at the left and the centre) by nuclei DAPI and actin TRITC-phalloidine staining, and SEM images (at the right) of the captured PC-3 cells.

(d,e) Optical images, and (f,g) fluorescent microscopy images of Chlamy cells inkjet printed onto Si NWs, at 230 min (panels (d) and (f)), and at 300 min (panels (e) and (g)), showing core-inserted, cytoplasm-inserted, and non-inserted cells.
