Installation and removal of the AFM tip are time-consuming processes, rendering them unsuitable for widespread use in quantitative tip wear

Additionally, the use of sharp structures allows for in-situ characterization of the tip, overcoming the disadvantage of needing to disassemble the tip for examination with a scanning electron microscope.
