Query: Electrospun nanofibers of polyCD/PMAA polymers and their potential
  application as drug delivery system   Herein, we used an electrospinning process to develop highly efficacious and
hydrophobic coaxial nanofibers based on poly-cyclodextrin (polyCD) associated
with poly(methacrylic acid) (PMAA) that combines polymeric and supramolecular
features for modulating the release of the hydrophilic drug, propranolol
hydrochloride (PROP). For this purpose, polyCD was synthesized and
characterized, and its biocompatibility was assessed using fibroblast
cytotoxicity tests. Moreover, the interactions between the guest PROP molecule
and both polyCD and $\beta$CD were found to be spontaneous. Subsequently, PROP
was encapsulated in uniaxial and coaxial polyCD/ PMAA nanofibers. A lower PROP
burst effect (reduction of approximately 50%) and higher modulation were
observed from the coaxial than from the uniaxial fibers. Thus, the coaxial
nanofibers could potentially be a useful strategy for developing a controlled
release system for hydrophilic molecules.
