The pH-sensitive polyampholyte nanogels: Inclusion of carbon nanotubes for improved drug loading

- Polyampholyte nanogel was prepared using carbon nanotubes as capping agent.
- The prepared nanogel is hydrophilic in nature and contains charged ions in the backbone.
- Incorporation of carbon nanotubes improved physicochemical properties of nanogels.
- These nanogels were biocompatible and clearly showed pH responsive behavior.
- The material is useful for water-based drug loading and pH responsive releasing.
