Biomedical potential of clay nanotube formulations and their toxicity assessment

Introduction: Halloysite clay nanotubes (HNTs) are a naturally abundant and biocompatible aluminosilicate material with a structure able to encapsulate 10-20% of drugs. These features are attractive toward the clinical application in controlled drug delivery, tissue engineering and regenerative medicine. Areas covered: We describe the application of HNTs as a viable method for clinical purposes, particularly developing formulations for...
