Cyclodextrin facilitated electrospun chitosan nanofibers

Abstract

Cyclodextrin complexation of chitosan presents a novel route to achieve nanofibers of chitosan and other difficult-to-electrospin biopolymers.

Cyclodextrin short-nanofibers using sacrificial electrospun polymeric matrix for VOC removal

“…The PEO polymeric matrix helps the continuous electrospinning process and higher amount of γ-CD facilitated the uniform and beadfree fiber formation mostly due to high solution viscosity. These results correlates with our previous reports [20,21] and other literature [22] where the presence of CD assist the formation of bead-free fibers from lower polymer solutions.…”

A Spectroscopic Study of Solid-Phase Chitosan/Cyclodextrin-Based Electrospun Fibers

“…The judicious choice of additive components offers a solution to offset such charge repulsion effects during electrospinning [4,7,[26][27][28][29][30]. For example, Burns et al reported the use of trifluoroacetic acid (TFA) and hydroxypropyl β-cyclodextrin (HPCD) as additives to assist in the electrospinning of chitosan nanofibers [31]. The potential of HPCD to form noncovalent host-guest complexes with various molecular species, in conjunction with the polyelectrolyte nature of chitosan, may further enhance the utility of such nanofibrous materials as advanced coating materials [31,32].…”

Delayed Dissolution and Small Molecule Release from Atomic Layer Deposition Coated Electrospun Nanofibers

“…Nanofibers are a unique class of materials which combine many desirable properties, including tunable mat porosity, a high surface area to volume ratio, and controlled surface functionality . These defining characteristics have generated diverse applications for nanofibers in areas ranging from filtration, energy, sensing, packaging, and biotechnology . Additionally, during nanofiber spinning, the fiber matrix can be loaded with molecules or particles to be finely tuned for a desired application.…”
