A Drug Delivery System Based on Polymer Nanotubes

A generic drug delivery system based on polymer nanotubes was design. Polymer nanotube bundles were used as drug delivery channels within a device. Because this device is very small and biocompatible, it can be implanted at any specific infectious location. The drug diffusion within the device was analyzed using the finite element method and the diffusion rate was calculated using Fick's law. The results showed the possibility of using this polymer-nanotube device as a drug delivery system that can provide a constant delivery rate and target a specific location.
