The malondialdehyde (MDA)-specific detection probe (MDA-6) was successfully synthesised through the photoinduced electron transfer (PET) mechanism which possesses many biological applications. In vivo biological applicability of this probe was proved in different cell lines, zebrafish and mice. In these models, the MDA was produced by oxygen stress injury and the relationship between MDA and probe were evaluated in vitro as well as in vivo under different stress conditions. After comparing evaluated results with commercial MDA kit, MDA-6 was concluded with high specificity, low limit of detection (0.03 μM), and can achieve micro-detection of MDA with low cytotoxicity, demonstrating MDA-6 enables safe and effective detection.
