Alginate films with different degrees of crosslinking obtained by internal and external gelation method and alginate films incorporated with oregano essential oil were prepared. The effect of mechanism of gelation and the incorporation of oregano essential oil on their optical, mechanical, antibacterial, microstructural and water vapor barrier properties were evaluated. The films subjected to e...

A calixarene-based supramolecular hydrogel with a porous network structure was successfully constructed via a hierarchical induced assembly strategy, showing reversible or irreversible gelation behaviors in response to several external stimuli including thermal, redox and ionic strength.

This paper describes a microfluidic device for the microencapsulation of cells in alginate beads to enhance cell viability. The alginate droplet including cells was gelified with calcified oleic acid, using two-phase microfluidics. The on-chip gelation had generated monodisperse spherical alginate beads, which could not be readily obtained via conventional external gelation in a calcium chlorid...

Alginate hydrogels are commonly used in biomedical applications such as scaffolds for tissue engineering, drug delivery, and as a medium for cell immobilisation. Multivalent cations are often employed to create physical crosslinks between carboxyl and hydroxyl moieties on neighbouring polysaccharide chains, creating hydrogels with a range of mechanical properties. This work describes the manufa...

The utility of an external structure-directing agent to induce orthogonal H-bonding-mediated programmed supramolecular-assembly and gelation of an n-type NDI chromophore is reported. Further, the effect of π-stacking and morphology on electrical conductivity of semiconducting NDI building blocks is revealed.
