Determination of Optimal Curing Conditions for Imaging Single Lung Cancer Cells by Atomic Force Acoustic Microscope

This paper presents a method for the determination of optimal curing conditions for the imaging of single lung cancer cells by atomic force acoustic microscope (AFAM). The cellular morphology, height and surface roughness of the cells treated with different concentrations of paraformaldehyde and methanol and durations were observed using an AFAM. The experimental results showed that the A549 cells solidified with 4% paraformaldehyde for the period from 30min to 60min were close to the profiles of living cells. The cells solidified with 4% paraformaldehyde for 10min were beneficial to obtain subsurface structures.
