Alginate-coating of artemisinin-loaded cochleates results in better control over gastro-intestinal release for effective oral delivery

Shuddhodana; Judeh, Zaher

Development of new drug delivery systems for effective delivery of poorly water-soluble drugs is important. We report the development of cochleate-based formulation for the oral administration of poorly water-soluble artemisinin (ART). Cochleates offer great potential as vehicles for the oral delivery of ART due to their high drug encapsulation and…

Hierarchical self-assembly of 3D lattices from polydisperse anisometric colloids

Luo, Binbin; Kim, Ahyoung; Smith, John W.; Ou, Zihao; Wu, Zixuan; Kim, Juyeong; Chen, Qian

Anisometric colloids—which have both nanometer and micrometer dimensions—combine features of their two constituent length scales. Here, using optical microscopy and modeling, the authors find that highly polydisperse anisometric colloids self-assemble into 3D, periodic lattices in a manner hardly inaccessible to nano- or micron-scale…

Topochemical polymerization of hierarchically ordered diacetylene monomers within the block copolymer domains

Krishnan, Deepthi; B, Amal Raj R.; Gowd, E. Bhoje

Integration of polymerizable small molecules within block copolymer based supramolecules provides a new strategy to generate functional materials. Herein we report hydrogen-bonding complexes of photopolymerizable 10,12-pentacosadyionic acid (PCDA) and polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP). We systematically investigate how annealing conditions affect the hierarchical ordering and…

Self-healing materials have attracted considerable attention because of their improved safety, lifetime, energy efficiency and environmental impact. Supramolecular interactions have been extensively considered in the field of self-healing materials due to their excellent reversibility and sensitive responsiveness to environmental stimuli. However, development of a polymeric material with good…

DMC-derived poly (ether urethanes) were prepared via isocyanate-free route. The transurethanization reaction of the non-isocyanate route needs higher temperature as compared with the traditional route. There may be some unknown side reactions under high temperature which lead to changes in chemical structure and subsequent thermal and mechanical properties of the…

Light-induced healing in azobenzene bridged silsesquioxanes

Galante, María J.; Zucchi, Ileana A.; Oyanguren, Patricia A.; Sáiz, Luciana M.

Intrinsic healable polymers are materials capable of repairing itself through its chemical nature, in order to improve stability and durability and to restore the lost functionalities or properties. In this study, azobenzene (AZO) moieties were incorporated into a previously reported bridged silsesquioxane based on the reaction of isocyanatepropyltriethoxysilane (IPTS) with…

De-symmetrizing periodically grafted amphiphilic copolymers: design, synthesis and generation of Janus folded chains

Sarkar, Ramkrishna; Gowd, E. Bhoje; Ramakrishnan, S.

Periodically grafted amphiphilic copolymers (PGACs) were earlier shown to fold in a zigzag fashion to enable segregation of the two immiscible segments, namely the backbone and the pendant segments; crystallization of one or both segments led to the formation of a lamellar structure with the two segments located in alternate…
