Multiwalled Nanotubes Formed by Catanionic Mixtures of Drug Amphiphiles

Mixing of oppositely charged amphiphilic molecules (catanionic mixing) offers an attractive strategy to produce morphologies different from those formed by individual molecules. We report here on the use of catanionic mixing of anticancer drug amphiphiles to construct multiwalled nanotubes containing a fixed and high drug loading. We found that the molecular mixing ratio, the solvent compositio...

New mesophases formed by water soluble discoidal amphiphiles

2014 We present the first examples of lyotropic discotic nematic and columnar (hexagonal) mesophases obtained by dissolution of non-ionic, disk-like amphiphilic mesogens (hexa-polyethyleneoxy derivatives of triphenylene) in water. The phenomenon of « solvent driven aggregation » is shown to be a practicable route to new and novel mesophases with structures and properties intermediate to and enc...

Theoretical insights into the adsorption behavior of CO molecules on the pure and Vn-doped BN nanotubes

Interaction of pure and Vn-doped (8, 0), (12, 0) and (16, 0) boron nitride nanotubes with CO molecules was studied using B3LYP/6-311++G(d) theoretical level. Substituting V instead of B atoms, increased the reactivity of nanotube. From the results, the complex stability depends on the direction and the number of the CO molecules interacted with the nanotube. In this work, the quantum...

Extracellular matrix formation in self-assembled minimalistic bioactive hydrogels based on aromatic peptide amphiphiles

The hitherto inconsistency in clinical performance for engineered skin drives the current development of novel cell-scaffolding materials; one challenge is to only extract essential characteristics from the complex native ECM (extracellular matrix) and incorporate them into a scaffold with minimal complexity to support normal cell functions. This study involved small-molecule-based bioactive hy...
