Published: April 2003

Using theoretical models, we undertake the first investigation into the synergy and rich phase behavior that emerges when binary particle mixtures are blended with microphase-separating copolymers. We isolate an example of spontaneous hierarchical self-assembly in such hybrid materials, where the system exhibits both nanoscopic ordering of the particles and macroscopic phase transformation in the copolymer matrix. Furthermore, the self-assembly is driven by entropic effects involving all the different components. The results reveal that entropy can be exploited to create highly ordered nanocomposites with potentially unique electronic and photonic properties.

Epigallocatechin gallate (EGCG), an important active component extracted from green tea, has attracted much attention due to its multiple biological activities such as antioxidant, antibacterial, anti-inflammatory, and antitumor effects. Meanwhile, metformin (Met), a classic drug for the treatment of type 2 diabetes, exhibits additional benefits such as hypoglycemic, antioxidant, anti-inflammatory, and antitumor effects. However, metformin often causes gastrointestinal reactions when used alone, affecting patients' quality of life.

A pea protein isolate (PPI)-hyaluronic acid (HA) nanocarrier delivery system was created for quercetin (Que) encapsulation using the pH conversion strategy. The self-assembly of the PPI-HA binary nanocomplex (HPP) were mainly driven by electrostatic and hydrophobic interactions. Que was successfully encapsulated in HPP nanocomposites (Que@HPP), which exhibited preferable redispersibility, and encapsulation efficiency (87.

Multicomponent self-assembly has been explored to create novel metamaterials from nanoparticles of different sizes and compositions, but the assembly of nanoparticles with complementary shapes remains rare. Recent binary assemblies were mediated by DNA base pairing or induced by solvent evaporation. Here, we introduce depletion-induced self-assembly (DISA) as a novel approach to constructing tunable binary lattices.

Wound healing is a challenging due to the presence of bacterial infection, excessive inflammation and angiogenesis disorders. While traditional therapies struggle, a functional hydrogel can effectively repair wounds. However, the use of hydrogels is limited due to their high swelling and excessive dehydration characteristics.

Hypothesis: Supra-particle formation by evaporation of an aqueous aerosol droplet containing nano-colloidal particles is challenging to investigate but has significant applications. We hypothesise that the Peclet number, Pe, which compares the effectiveness of evaporation-induced advection to that of colloidal diffusion, is critical in determining supra-particle morphology and can be used to predict the dried morphology for droplet containing polydisperse nanoparticles.

Experiments: Sterically-stabilized diblock copolymer nanoparticles were prepared via polymerization-induced self-assembly (PISA).
