چکیده

A novel supramolecular star polymer is reported, which can be prepared either from atom-transfer radical polymerization (ATRP) of a self-assembled initiator or from self-assembly of a guanosine-capped linear polymer.

ATP hydrolysis by a domain related to translation factor GTPases drives polymerization of a static bacterial morphogenetic protein.

The assembly of static supramolecular structures is a culminating event of developmental programs. One such structure, the proteinaceous shell (called the coat) that surrounds spores of the bacterium Bacillus subtilis, is composed of about 70 different proteins and represents one of the most durable biological structures known. The coat is built atop a basement layer that contains an ATPase (Sp...

Supramolecular block copolymers by kinetically controlled co-self-assembly of planar and core-twisted perylene bisimides

New synthetic methodologies for the formation of block copolymers have revolutionized polymer science within the last two decades. However, the formation of supramolecular block copolymers composed of alternating sequences of larger block segments has not been realized yet. Here we show by transmission electron microscopy (TEM), 2D NMR and optical spectroscopy that two different perylene bisimi...

Fabrication of Thermoresponsive Cross-Linked Poly(N-isopropylacrylamide) Nanocapsules and Silver Nanoparticle-Embedded Hybrid Capsules with Controlled Shell Thickness

Hollow polymeric nanocapsules have attracted great interest in recent years due to their broad applications in controlledrelease carriers, catalysis, nanoreactors, and encapsulation of guest molecules. Polymeric nanocapsules have been typically fabricated via the selfassembly of block copolymers, 5 polymerization within lipid vesicles, emulsion polymerization, 14 and the sacrificial core-templa...
