We studied the effect of the exposure of human A549 and SH-SY5Y cell lines to aqueous solutions of organic/inorganic halide perovskites CHNHPbI (MAPbI) and CHNHSnI (MASnI) at the molecular level by using Fourier transform infrared microspectroscopy. We monitored the infrared spectra of some cells over a few days following exposure to the metals and observed the spectroscopic changes dominated by the appearance of a strong band at 1627 cm. We used Infrared (IR) mapping to show that this change was associated with the cell itself or the cellular membrane.

Article Synopsis
  • The research evaluates the health hazards of the lead halide perovskite CHNHPbI, which is used in solar cells, by testing its effects on various human and murine cell types.
  • In experiments, CHNHPbI caused significant cell death in hippocampal neurons and neuroblastoma cells, while lung epithelial cells experienced altered growth and structure without dying.
  • The study emphasizes the need for further investigation into the potential health and environmental risks associated with both short-term and long-term exposure to CHNHPbI.
