Physiological conditions of biological samples are regulated by many different parameters including mechanical and biochemical factors etc. Single-cell studies of these parameters are challenging by using conventional bioanalysis methods. However, with the recent advancement in nanotechnology, single-molecule and single-cell analysis is much more accessible. Understanding the changes of neuroblastoma cells in different mechanisms is critical for fundamental research in neurosciences. Here, we investigate the mechanical behavior of SH-SY5Y cells using atomic force microscopy. Topographic imaging of the cells and real-time quantitative analysis of their mechanical properties will be presented in the paper. Copyright © 2013 IEEE.
