Electrospinning: Small 13/2009

The cover picture shows the novel structure of a single electrospun polyurethane fiber containing two distinct fluorescently labeled proteins, texas red-labeled bovine serum albumin (red) and alexafluor 488-labeled epidermal growth factor (green), as separated domains. This structure is fabricated using the combination of two techniques, electrospinning and encapsulation of bioactive compound using nanoparticles. For more information, please read the Communication “Encapsulation of Multiple Biological Compounds Within a Single Electrospun Fiber” by G. E. Wnek et al., beginning on page 1508.
