Higher quality quercetin sustained release ethyl cellulose nanofibers fabricated using a spinneret with a Teflon nozzle

- A new spinneret with Teflon nozzle for implementing electrospinning.
- The Teflon nozzle facilitates energy transfer to the working fluid.
- New knowledge about the interfacial interactions between Teflon/metal and fluids.
- Producing quercetin-loaded composite fibers with higher quality.
- Nanofibers from the new protocols provide better sustained drug release profile.
