Spongy Gels by a Top-Down Approach from Polymer Fibrous Sponges

Ultralight cellular sponges offer a unique set of properties. We show here that solvent uptake by these sponges results in new gel-like materials, which we term spongy gels. The appearance of the spongy gels is very similar to classic organogels. Usually, organogels are formed by a bottom-up process. In contrast, the spongy gels are formed by a top-down approach that offers numerous advantages for the design of their properties, reproducibility, and stability.

Unlocking Nanocarriers for the Programmed Release of Antimalarial Drugsa

A. R. Bagheri, S. Agarwal, J. Golenser, A. Greiner Global Challenges 2017, DOI: 10.1002/gch2.201600011.


A programmable release system with wide range of release profiles of the antimalarial artemisone (ART) from fibrous nanocarriers (NFN) is presented. This is achieved following a new paradigm of using ART-loaded NFN in infusion system of hydrophobic drug eluting nanocarriers, adapted to clinical applications. Very importantly, under these conditions ART did not degrade as it was observed in solution.
