Abstract:
Multicore-shell nanofibers were fabricated by integrating emulsion electrospinning and coaxial electrospinning technologies, in which the multicore section of the nanofibers was prepared by electrospinning of gelatin-stabilized emulsions, and the shell layer was coaxially electrospun from zein solution. Coaxial electrospinning of zein helped form emulsion-based electrospun fibers with bead-in-string, spindle-like, and straight morphologies. The hydrogen bonding between gelatin and zein contributed to the enhanced thermal properties of coaxially electrospun nanofibers. The coating of zein as shell greatly improved fiber surface wettability and mechanical strength. The release behavior of curcumin from the nanofibers was dominated by Fickian diffusion, and the zein shell as a physical barrier favored the prolonged release of curcumin and then the long-lasting antibacterial activity towards Escherichia coli. This work thus gives an insight into the development of the nanofibers by emulsion-coaxial electrospinning as encapsulation matrices for the application in food products.

The Extracellular Matrix
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...
