Mesoporous silica nanoparticles (MSNs) have been used as an anticancer drug delivery system with high safety and entrapment capacity thanks to their large internal space for drug accommodation, durable structure, and good biocompatibility. However, the treatment efficiency of the bare MSNs is limited due to its drug leakage and burst release. In this study, a phospholipid bilayer was covered on the MSNs surface (MSN@Lip) as a liposomal cap that not only reduced drug leakage but also improved the stability of the colloidal system.

Ebook "Protein dimerization and oligomerization in biology" has a strong focus on homo-oligomerization, which is surprisingly common. However, protein function is so often linked to both homo- and hetero-oligomerization and many heterologous interactions likely evolved from homologous interaction, so this volume also covers many aspects of hetero-oligomerization.
