Abstract
The surface functionalization of polymer-mediated drug/gene delivery holds immense potential for disease therapy. However, the design principles underlying the surface functionalization of polymers remain elusive. In this study, we employed computer simulations to demonstrate how the stiffness, length, density, and distribution of polymer ligands influence their penetration ability across the cell membrane. Our simulations revealed that the stiffness of polymer ligands affects their ability to transport cargo across the membrane. Increasing the stiffness of polymer ligands can promote their delivery across the membrane, particularly for larger cargoes. Furthermore, appropriately increasing the length of polymer ligands can be more conducive to assisting cargo to enter the lower layer of the membrane. Additionally, the distribution of polymer ligands on the surface of the cargo also plays a crucial role in its transport. Specifically, the one-fourth mode and stripy mode distributions of polymer ligands exhibited higher penetration ability, assisting cargoes in penetrating the membrane. These findings provide biomimetic inspiration for designing high-efficiency functionalization polymer ligands for drug/gene delivery.

Abstract
The influence of surface functions on the interactions between Poly(PhosphorHydrazone) PPH dendrimers and human monocytes is discussed on the basis of complementary biological and physicochemical studies on membrane models (monolayers and multi-lamellar vesicles). The studies were performed on both an active and non-toxic phosphonic acid capped dendrimer and a non-active but toxic carboxylic acid capped one. On the one hand, comparative studies of the behaviour of DPPC monolayers in the presence or absence of PPH dendrimers in the subphase showed differences in the phase transitions, highlighting interactions between both dendrimers and phospholipid monolayers, with a larger incidence for the carboxylic acid capped dendrimer (negative control), validating its cellular toxicity. On the other hand, comparative biological studies (activation of human monocytes and binding of fluorescent dendrimers on human monocytes) show the pre-eminence of phosphonic acid capped dendrimers towards specific binding and subsequent activation of human monocytes.

Abstract
Most therapeutic agents suffer from poor solubility, rapid clearance from the blood stream, a lack of targeting, and often poor translocation ability across cell membranes. Drug/gene delivery systems (DDSs) are capable of overcoming some of these barriers to enhance delivery of drugs to their right place of action, e.g. inside cancer cells. In this review, we focus on nanoparticles as DDSs. Complementary experimental and computational studies have enhanced our understanding of the mechanism of action of nanocarriers and their underlying interactions with drugs, biomembranes and other biological molecules. We review key biophysical aspects of DDSs and discuss how computer modeling can assist in rational design of DDSs with improved and optimized properties. We summarize commonly used experimental techniques for the study of DDSs. Then we review computational studies for several major categories of nanocarriers, including dendrimers and dendrons, polymer-, peptide-, nucleic acid-, lipid-, and carbon-based DDSs, and gold nanoparticles. This article is part of a Special Issue entitled: Membrane Proteins edited by J.C. Gumbart and Sergei Noskov.
