 Cell membrane coding technology is an emerging field of research that seeks to mimic the properties of natural cell membranes in order to create more effective and longer-lasting nanoparticle-based drug delivery systems. This technology has been shown to improve the biocompatibility of nanoparticles while increasing their circulation time in vivo, making them ideal candidates for targeted drug delivery. Despite its potential, however, much work remains before it can be applied in clinical practice. This article was authored by Yao Lu, Jingxian Luo, Xiaojia Chen, and others.
