Опубликована: Дек. 21, 2021

The integration of bioactive materials (e.g., proteins and genes) into nanoparticles holds promise in fields ranging from catalysis to biomedicine. However, it is challenging develop a simple broadly applicable nanoparticle platform that can readily incorporate distinct biomacromolecules without affecting their intrinsic activity. Herein, metal-phenolic assembly approach presented whereby diverse functional be assembled water by combining various synthetic natural building blocks, including poly(ethylene glycol), phenolic ligands, metal ions, macromolecules. process primarily mediated complexes through coordination hydrophobic interactions, which yields uniform spherical (mostly <200 nm), while preserving the function incorporated (siRNA five different used). functionality demonstrated cancer cell apoptosis, RNA degradation, catalysis, gene downregulation studies. Furthermore, resulting used as blocks for secondary engineering superstructures via templating cross-linking with ions. bioactivity versatility potentially streamlined rational design future materials.

Abstract The first-order phase transition between two tetrahedral networks of different density—introduced as a hypothesis to account for the anomalous behaviour certain thermodynamic properties deeply supercooled water—has received strong support from growing body work in recent years. Here we show that this liquid–liquid can be described an unentangled, low-density liquid and entangled, high-density liquid, latter containing ensemble topologically complex motifs. We first reveal distinction rationally designed colloidal analogue water. water model displays well-known anomalies well critical point. then investigate water, employing widely used molecular models, demonstrate there is also clear topological its networks, thereby establishing generality observation, which might have far-reaching implications understanding transitions liquids.
