Abstract
Herein, a mitochondrial targeted fluorescent nitrite peroxide probe CHP for dynamic monitoring of cellular lung injury was developed. For the practical delivery and selectivity, the structural features including pyridine head and borate recognition group were selected. CHP could respond to ONOO- with the 585 nm fluorescence signal. The detecting system indicated advantages such as wide linear range (0.0-30 μM), high sensitivity (LOD = 0.18 μM), high selectivity and steadiness under different environmental conditions including pH (3.0-10.0), time (48 h) and medium. In living A549 cells, the response of CHP towards ONOO- showed dose-dependent and time-dependent tendencies. The co-localization suggested that CHP could achieve mitochondrial targeting. Moreover, CHP could monitor the variation of endogenous ONOO- level and the cellular lung injury induced by LPS.

Abstract
Extracellular vesicles (EVs) are nanosized vesicles released from most cell types that play a key role in cell-to-cell communication by carrying DNA, non-coding RNAs, proteins and lipids out of cells. The composition of EVs depends on the cell or tissue of origin and changes according to their pathophysiological conditions, making EVs a potential circulating biomarker of disease. Additionally, the natural tropism of EVs for specific organs and cells has raised the interest in their use as delivery vehicles. In this review, we provide an overview of EV biogenesis, isolation and characterization. We also discuss EVs in the context of endothelial pathophysiology, summarizing the current knowledge about their role in cell communication in quiescent and activated endothelial cells. In the last part, we describe the potential use of EVs as delivery vehicles of bioactive compounds and the current strategies to load exogenous cargo and to functionalize EVs to drive them to a specific tissue.
