(a) Modified atomic force microscopy (AFM) tip for penetration into a single cell to measure the mechanical properties of a cell nucleus (adapted with permission from Ref. 19; Copyright (2014) American Chemical Society). (b) The electron beam-induced growth of AFM nanoneedles was used to penetrate into corneocytes. Reproduced with permission from Ref. 60. (c) A single multi-walled carbon nanotube (MWCNT) attached to a pyramidal tip. Reproduced with permission from Ref. 61. (d) SEM and TEM images of MWCNT and single-walled carbon nanotubes (SWCNT) fabricated by chemical vapor deposition and assembled onto a silicon cantilever/tip. Reproduced with permission from Ref. 62.
