Organic acids interacting with block copolymers have broadened the window that retains isoporous structures

Evaporation is significantly important for the preparation of isoporous membranes from self-assembly and non-solvent induced phase separation (SNIPS). Unfortunately, the time of solvent evaporation that retains isoporous structures is usually rather short, which causes many challenges to fabricate membranes with repeatable and controllable isoporous structures. In the current work, we…

Precise Self-Assembly of Nanoparticles into Ordered Nanoarchitectures Directed by Tobacco Mosaic Virus Coat Protein

Zhang, Jianting; Zhou, Kun; Zhang, Yejun; Du, Mingming; Wang, Qiangbin

Self-assembly guided by biological molecules is a promising approach for fabricating predesigned nanostructures. Protein is one such biomolecule possessing deterministic 3D crystal structure and peptide information, which acts as a good candidate for templating functional nanoparticles (fNPs). However, inadequate coordination efficacy during the establishment of interfacial interactions with fNPs…

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…
