Figure 1: Characterization of SNPs.
From: New findings of silica nanoparticles induced ER autophagy in human colon cancer cell
The sizes of SNPs were evaluated by SEM (a) and TEM (b). The SNPs exhibit a near-spherical shape with good dispersibility. (c) The size distribution of SNPs by SEM. The average diameter of the SNPs is roughly 86 nm. (d) The stability of SNPs dissolved in PBS, DMEM, and FBS after 48 h, 72 h, and 2 months, respectively.
