In a groundbreaking study, researchers from Xiamen University (China) have uncovered the detrimental effects of quantum dots (QDs) on the retinal health of zebrafish. Quantum dots, known for their unique optical properties and widespread use in various technologies, have now been shown to cause significant retinal degeneration.

The study focused on InP/ZnS quantum dots and their impact on zebrafish retina. The researchers discovered that exposure to these QDs leads to retinal degeneration through two key processes: ferroptosis and mitophagy. Ferroptosis is a type of cell death driven by iron-dependent lipid peroxidation, while mitophagy involves the selective degradation of mitochondria by autophagy.

The researchers used our 437 nm Cobolt laser as part of their imaging techniques as the excitation source for the Raman spectra.

This discovery offers potential pathways for preventing or treating the adverse effects of QDs on retinal health, providing valuable insights into the mechanisms of QD-induced retinal degeneration, which, in turn, emphasizes the need for further investigation into the safety of these nanoparticles in consumer products.
