Abstract

Boron nitride nanospheres (BNNS) have attracted increasing attention in many fields due to their unique physicochemical properties. Biomedical application of BNNS has also been explored recently. However, limited by the hydrophobicity and poor dispersity of BNNS, their biocompatible performance especially the in vivo biosafety has rarely been reported and is still unclear now. In this work, BNNS were firstly camouflaged with red blood cell membrane by physical extrusion (CM-BNNS). CM-BNNS were then incubated with cells as well as intravenously injected into the mice to uncover their potential in vitro and in vivo toxicity. Results were promising as CM-BNNS exhibited better dispersion and stability compared with pristine BNNS. In vitro data demonstrated the relatively enhanced biosafety of CM-BNNS. The red blood cell membrane coating endowed BNNS with markedly prolonged blood circulation and decreased accumulation in the lung. In addition, CM-BNNS showed no adverse effects on all the evaluated hematic parameters and tissues of treated mice at a dose of 10 mg/kg. Taken together, our work demonstrated the optimal biocompatibility of CM-BNNS and pave the way for their future biomedical applications.
