However, it can cause harm to humans. Thus, it is imperative to develop a convenient and effective detection method for hydrazine. Because Pyrenecarboxaldehyde is hydrophobic, it can aggregate in aqueous solution to form nanoparticle and emit fluorescence. And Pyrenecarboxaldehyde has an aldehyde group on pyrene ring, which has high activity towards hydrazine. In this work, we attempted to employ Pyrenecarboxaldehyde nanoparticle probe to monitor hydrazine. Probe has strong blue emission in aqueous solution. After adding hydrazine, the product forms amino group which leads to enhanced water solubility. Then, the product is dissolved in aqueous solution and the fluorescence disappears. It is proved in this work that probe exhibits high sensitivity with a low detection limit. In order to image hydrazine in vivo, liposome has been employed to prepare Pyrenecarboxaldehyde liposomal nanoparticle. Then, exploring the effect of liposomal nanoparticle probe on cell viability. The result shows the cell viability remains at a high level in different concentrations of liposome nanoparticle probes. This liposomal nanoparticle probe is suitable for cells imaging. The cells and zebrafishes which are incubated with liposomal nanoparticle probe display blue emission under the fluorescence microscope. After treating with hydrazine, the blue emission disappeared. This study shows that this scheme may have a good application prospect for detecting hydrazine in vivo. 查看全文查看/发表评论下载PDF阅读器 相关附件：支持信息(1).pdf支持信息.pdf版权转让声明书附件1 -->
