I want you to act as an academic journal editor Please rephrase the paragraph from an academic angle based on the writting style of the Nature journalThe morphology microstructure and mitochondrial da

The present study utilized transmission electron microscopy (TEM) to examine the morphology, microstructure, and mitochondrial damage of SH-SY5Y cells. To this end, the cells were exposed to PSNPs, collected via centrifugation (800 g), and fixed in 4% glutaraldehyde. Following this, they were fixed again using 1% OsO4 and subsequently embedded in Epon. Finally, ultra-thin sections were stained with uranyl acetate/lead citrate and examined using the Hitachi 7500 TEM.
