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.
纳米封装技术是药物输送领域的一项最新进展,可提高药物的稳定性、生物利用度,并实现对特定细胞或组织的可控、靶向物质输送。然而,传统的纳米颗粒输送面临着诸如循环时间短和免疫识别等挑战。为了解决这些问题,细胞膜包覆的纳米颗粒已被提议作为一种实用的替代方法。该生产过程包括三个主要阶段:细胞膜的裂解和膜碎片的形成、膜的分离和纳米颗粒的包覆。细胞膜通常使用低渗裂解与匀浆或超声处理进行碎片化。随后通过多次离心步骤分离膜碎片。可以通过挤出、超声处理或这两种方法的组合来包覆纳米颗粒。值得注意的是,这项分析表明,纳米颗粒包覆并没有一种普遍适用的方法,因为这三个阶段在程序上有很大的不同。本综述探讨了细胞膜包覆纳米颗粒的最新进展和方法,强调了它们作为靶向药物输送和各种治疗应用的有效替代方法的潜力。
