Responsive nanofibers with embedded hierarchical lipid self-assemblies

Tien, Nguyen D. ; Maurya, Anjani K. ; Fortunato, Giuseppino ; Rottmar, Markus ; Zboray, Robert ; Erni, Rolf ; Dommann, Alex ; Rossi, René M. ; Neels, Antonia ; Sadeghpour, Amin

In: Langmuir, 2020, vol. 36, no. 40, p. 11787–11797

We introduce the design and study of a hybrid electrospun membrane with a dedicated nanoscale structural hierarchy for controlled functions in the biomedical domain. The hybrid system comprises submicrometer-sized internally self-assembled lipid nanoparticles (ISAsomes or mesosomes) embedded into the electrospun membrane with a nanofibrous polymer network. The internal structure of ISAsomes, ...

Nanostructure generation during milk digestion in presence of a cell culture model simulating the small intestine

Hempt, Claudia ; Gontsarik, Mark ; Buerki-Thurnherr, Tina ; Hirsch, Cordula ; Salentinig, Stefan

In: Journal of Colloid and Interface Science, 2020, vol. 574, p. 430–440

Hypothesis: The development of advanced oral delivery systems for bioactive compounds requires the fundamental understanding of the digestion process within the gastrointestinal tract. Towards this goal, dynamic invitro digestion models, capable of characterising the molecular as well as colloidal aspects of food, together with their biological interactions with relevant invitro cell culture...

COFs meet graphene nanoribbons

Fritz, Patrick Walter ; Coskun, Ali

In: Chem, 2020, vol. 6, no. 5, p. 1046–1048

2D covalent organic frameworks (COFs) have received considerable attention because of their crystallinity, permanent porosity, and tunability, yet they exhibit low in-plane conductivity. In this issue of Chem, Fischer and co-workers report an approach for growing 2D COF thin films featuring high in-plane conductivity for potential use in organic electronics.
