Although nanomedicines can address significant shortcomings of conventional therapy, biological barriers remain a challenge in their delivery and accumulation at diseased sites. To achieve long circulation time, immune evasion, and targeted accumulation, conventional nanocarriers need modifications, e.g., PEGylation, peptide/aptamer attachment, etc. One such modification is a biomimetic coating using cell membrane (CM), which can offer long circulation or targeting, or both. This top-down CM coating process is facile and can provide some advantageous features over surface modification by synthetic polymers. Herein, an overview is provided on the engineering of CM camouflaged polymer nanoparticles. A short section on CM and the development of CM coating technology has been provided. Detailed description of the preparation and characterization of CM camouflaged polymer NPs and their applications in cancer treatment has been reported. A brief comparison between CM coating and PEGylation has been highlighted. Various targeting approaches to achieve tumor-specific delivery of CM coated NPs have been summarized here. Overall, this review will give the readers a nice picture of CM coated polymer NPs, along with their opportunities and challenges.</p></div>","PeriodicalId":33573,"journal":{"name":"Nano Materials Science","volume":"4 4","pages":"Pages 295-321"},"PeriodicalIF":9.9,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2589965121000933/pdfft?md5=8d3d36990ff02cb379d4f8f037f108b7&pid=1-s2.0-S2589965121000933-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47707440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that the ballistic limits can reach 75.4% of single-layer graphene (SLGR) at about 1/2 density, leading to approximately the same specific energy absorption (SEA) as SLGR. The ballistic limits of SLGDY and SLGR with single atomic thickness agree with the predictions of macroscopic penetration limits equations, implying the applicability of continuum penetration theories for two-dimensional (2D) materials. In addition, the dynamic responses involving stress wave propagation, conic deformation, and damage evolution are investigated to illuminate the mechanisms of the dynamic energy dissipation. The superior impact resistance of SLGDY and SLGR can be attributed to both the ultra-fast elastic and conic waves and the excellent deformation capabilities.
