Summary of "Rod-coil block copolymer aggregates via polymerization-induced self-assembly."

Polymerization-induced self-assembly (PISA), incorporating the polymerization with in situ self-assembly, can achieve nano-objects efficiently. However, the cooperative polymerization and self-assembly lead to unclear polymerization kinetics and aggregation behavior, especially for the systems forming rigid chains. Here, we used dissipative particle dynamics simulations with a probability-based reaction model to explore the PISA behavior of rod-coil block copolymer systems. The impact of the length of macromolecular initiators, the targeted length of rigid chains, and the reaction probability on the PISA behavior, including polymerization kinetics and self-assembly, were examined. The difference between PISA and traditional self-assembly was revealed. A comparison with experimental observations shows that the simulation can capture the essential feature of the PISA. The present work provides a comprehensive understanding of rod-coil PISA systems and may provide meaningful information for future experimental research.

Medical and Biotech [MESH] Definitions

Copolymer of divinyl ether and maleic anhydride that acts as an immunostimulant with antineoplastic and anti-infective properties. It is used in combination with other antineoplastic agents.

Interruption of sympathetic pathways, by local injection of an anesthetic agent, at any of four levels: peripheral nerve block, sympathetic ganglion block, extradural block, and subarachnoid block.

Impaired conduction of cardiac impulse that can occur anywhere along the conduction pathway, such as between the SINOATRIAL NODE and the right atrium (SA block) or between atria and ventricles (AV block). Heart blocks can be classified by the duration, frequency, or completeness of conduction block. Reversibility depends on the degree of structural or functional defects.

Cements that act through infiltration and polymerization within the dentinal matrix and are used for dental restoration. They can be adhesive resins themselves, adhesion-promoting monomers, or polymerization initiators that act in concert with other agents to form a dentin-bonding system.

A tripartite motif protein that consists of an N-terminal pyrin domain, a central coiled-coil region and B-box type ZINC FINGER, and C-terminal regions that mediate homotrimerization and interactions with other proteins (the B30.2/SPRY DOMAIN). It is expressed primarily by mature GRANULOCYTES and associates with the cytoskeleton in the perinuclear area as well as AUTOPHAGOSOMES, where it co-ordinates the assembly of AUTOPHAGY-RELATED PROTEINS and degradation of INFLAMMASOME components. It functions in INNATE IMMUNITY and INFLAMMATION; mutations in the Pyrin protein (MEFV) gene are associated with FAMILIAL MEDITERRANEAN FEVER.
