From an article by nanotechnology now:
New research led by the University of Liverpool aims to improve the administration and availability of drug therapies to HIV patients through the use of nanotechnology.
The research, conducted by the collaborative nanomedicine research programme led by Pharmacologist Professor Andrew Owen and Materials Chemist Professor Steve Rannard, examined the use of nanotechnology to improve the delivery of drugs to HIV patients.
Nanotechnology is the manipulation of matter on an atomic, molecular, and supramolecular scale. Nanomedicine is the application of nanotechnology to the prevention and treatment of disease in the human body. This evolving discipline has the potential to dramatically change medical science and is already having an impact in a number of clinically used therapies and diagnostics worldwide.
