Abstract
Nanobiotechnology such as atomic force microscopy (AFM) has a great application in various regimes of cell biology, offering an excellent avenue to study cellular nanotopography, nanomechanics, and nanointeraction. AFM nanotopography can provide a high resolution of nano-architectures of different cells. AFM nanomechanics have shed new light on characterizing mechanical properties of cellular structures and biological materials as well as monitoring the physiopathological processes. AFM nanointeraction measurement helps the understanding of the molecular interaction forces at a nanoscale.
