摘      要：Biomimetic nanoengineering presents great potential in biomedical research by integrating cell membrane(CM) with functional nanoparticles. However, preparation of CM biomimetic nanomaterials for custom applications that can avoid the aggregation of nanocarriers while maintaining the biological activity of CM remains a challenge. Herein, a high-performance CM biomimetic graphene nanodecoy was fabricated via purposeful surface engineering, where polyethylene glycol(PEG) was used to modifying magnetic graphene oxide(MGO) to improve its stability in physiological solution, so as to improve the screening efficiency to active components of traditional Chinese medicine(TCM). With this strategy, the constructed PEGylated MGO(PMGO) could keep stable at least 10 days, thus improving the CM coating efficiency. Meanwhile, by taking advantage of the inherent ability of He La cell membrane(HM) to interact with specific ligands, HM-camouflaged PMGO showed satisfied adsorption capacity(116.2 mg/g) and selectivity. Finally, three potential active components, byakangelicol, imperatorin,and isoimperatorin, were screened from Angelica dahurica, whose potential antiproliferative activity were further validated by pharmacological studies. These results demonstrated that the purposeful surfaceengineering is a promising strategy for the design of efficient CM biomimetic nanomaterials, which will promote the development of active components screening in TCM.
