Surfactant-aided electrospraying of low molecular weight carbohydrate polymers from aqueous solutions

In this work it is demonstrated, for the first time, that it is feasible to develop, using the electrospraying technique, low molecular weight carbohydrate-based capsule morphologies from aqueous solutions through the rational use of surfactants. Two different low molecular weight carbohydrate polym...

The morphology and molecular organization of the structures obtained was characterized and related to the solution properties.
