    纳米封装已成为药物递送的最新进展,增强稳定性,生物利用度,并实现受控,靶向物质递送到特定细胞或组织。然而,传统的纳米颗粒递送面临着循环时间短和免疫识别等挑战。为了解决这些问题,细胞膜包被的纳米颗粒已被建议作为一种实用的替代品。生产过程涉及三个主要阶段:细胞裂解和膜破碎,膜隔离,和纳米粒子涂层。通常使用均质化或超声处理的低渗裂解将细胞膜片段化。通过多个离心步骤分离随后的膜片段。纳米粒子涂层可以通过挤出实现,超声处理,或两种方法的组合。值得注意的是,这一分析揭示了缺乏一种普遍适用的纳米粒子涂层方法,因为这三个阶段在程序上有很大不同。这篇综述探讨了细胞膜涂层纳米粒子的当前发展和方法,突出了它们作为靶向药物递送和各种治疗应用的有效替代方案的潜力。
    Nanoencapsulation has become a recent advancement in drug delivery, enhancing stability, bioavailability, and enabling controlled, targeted substance delivery to specific cells or tissues. However, traditional nanoparticle delivery faces challenges such as a short circulation time and immune recognition. To tackle these issues, cell membrane-coated nanoparticles have been suggested as a practical alternative. The production process involves three main stages: cell lysis and membrane fragmentation, membrane isolation, and nanoparticle coating. Cell membranes are typically fragmented using hypotonic lysis with homogenization or sonication. Subsequent membrane fragments are isolated through multiple centrifugation steps. Coating nanoparticles can be achieved through extrusion, sonication, or a combination of both methods. Notably, this analysis reveals the absence of a universally applicable method for nanoparticle coating, as the three stages differ significantly in their procedures. This review explores current developments and approaches to cell membrane-coated nanoparticles, highlighting their potential as an effective alternative for targeted drug delivery and various therapeutic applications.
