“…Here, we provide an interesting square-shaped confinement environment. The interface is formed by a hard particle surface and a soft homopolymer surface, not like in cylinder confinement [45,46] with two hard surfaces or in brush confinement with two soft surfaces. [47] The hard and soft surface confinements give rich structures of vesicles and micelles.…”

The self-assembly of diblock copolymers confined around one square-shaped particle is studied systematically within two-dimensional self-consistent field theory (SCFT). In this model, we assume that the thin block copolymer film is confined in the vicinity of a square-shaped particle by a homopolymer melt, which is equivalent to the poor solvents. Multiple sequences of square-shaped particle-induced copolymer aggregates with different shapes and self-assembled internal morphologies are predicted as functions of the particle size, the structural portion of the copolymer, and the volume fraction of the copolymer. A rich variety of aggregates are found with complex internal self-assembled morphologies including complex structures of the vesicle, with one or several inverted micelle surrounded by the outer monolayer with the particle confined in the core. These results demonstrate that the assemblies of diblock copolymers formed around the square-shaped particle in poor solvents are of immediate interest to the assembly of copolymer and the morphology of biomembrane in the confined environment, as well as to the transitions of vesicles to micelles.

“…For example, scientists introduced rigid substrates into the DPD simulation and studied the interaction of polymers on these substrates, − which is helpful in areas such as the development of biomedical antibacterial coatings. Some work has also focused on the self-assembly of polymers in rigidly confined condition, ,− and these works have enriched people’s knowledge in the field of self-assembly.…”

A nanocarrier drug delivery system, effectively assisting to improve the solubility, bioavailability, and targeting of drugs in the human body, is a crucial means for treating cancer and other diseases. However, drug carriers usually possess multiple components and complex microstructures, and studies on the formation mechanism and internal structural details of nanocarriers are still incomplete by experimental methods. In order to overcome this adversity, the dissipative particle dynamics (DPD) simulation has been widely used owing to its unique simulation time-space scale and satisfying computing efficiency. In the past decades, more and more kinds of complex nanocarriers with various structures have been successfully characterized, and influencing factors in mounting numbers have also been parametrized. Not only emphasizing on the self-assembly structure of nanocarriers, but the application area of DPD simulation has also become a complete system covering from the synthesis and preparation to interaction with the biomembrane. This article reviews the application of DPD simulations in drug delivery systems. We have established the connection between existing studies and proposed some outlooks for the further combination between DPD simulation and the design of a drug delivery system.

“…In the case of cylindrical pores in anodized alumina oxide (AAO) membranes, various helical structures were observed and they have been used as confining geometries (Lambooy et al, 1994;Dauphas et al, 2004;Wu et al, 2004;Xiang et al, 2004;Maiz et al, 2014;Hou et al, 2015). According to the theoretical prediction, more unusual morphologies like single helices, double helices, and meshes could be produced as shown in Figure 1C Yang et al, 2012;Bae et al, 2013;Xu et al, 2014;He et al, 2015;Zhang et al, 2015b;Zuo et al, 2015).…”

Block copolymers (BCPs) can create various morphology by self-assembly in bulk or film. Recently, using BCPs in confined geometries such as thin film (one-dimension), cylindrical template (two-dimension), or emulsion droplet (three-dimension), nanostructured BCP particles have been prepared, in which unique nanostructures of the BCP are formed via solvent annealing process and can be controlled depending on molecular weight ratio and interaction parameter of the BCPs, and droplet size. Moreover, by tuning interfacial property of the BCP particles, anisotropic particles with unique nanostructures have been prepared. Furthermore, for practical application such as drug delivery system, sensor, self-healing, metamaterial, and optoelectronic device, functional nanoparticles can be incorporated inside BCP particles. In this article, we summarize recent progress on the production of structured BCP particles and composite particles with metallic nanoparticles.
