This cover by John Lannutti and colleagues demonstrates electrospun 75:25 PCL:PET following 5s acetone exposure. The biomimetic “shish‐kebab” morphology is absent from pure PCL fibers following a similar acetone exposure, suggesting that the pattern of dissolution is strongly influenced by the presence of molecularly dispersed PET along the length of the fiber. Sintering of a tubular deposition of this composition at 100°C successfully produced a densified capsule that allowed for zero‐order drug release over a period of 8 days. The low temperature nature of the electrospinning process avoided copolymerization; DSC suggested a post‐sintering structure consisting of nanoscale PET dispersed in PCL following the original fiber direction.
