Abstract
OBJECTIVES
This study aimed at investigating cellular uptake pathways of carbon dots (CDs) in human adenoid cystic carcinoma cell line ACC-2.
MATERIALS AND METHODS
We synthesized CDs using a hydrothermal method with citric acid and polyethylenimine (PEI, Mw = 25 000). The CDs incubated with the ACC-2 cells showed their bioimaging capabilities using a confocal microscopy test. Flow cytometry was used to analyse cellular uptake pathways of CDs in ACC-2 cells.
RESULTS
Our findings indicated that CDs possessed good biocompatibility in ACC-2 cells. CDs were endocytosed mainly via micropinocytosis and energy-dependent pathways.
CONCLUSIONS
In general, these findings suggested that CDs had excellent biomedical imaging properties for ACC-2 cells and there was a potential opportunity to develop biomedical applications.
