[Hybrid nanocarriers for controlled delivery of antitumour and retroviral drugs delivery]

Abstract

The efficient delivery of drugs in the body requires the use of non-toxic nanocarriers. Most of the existing materials show poor drug loading and/or rapid release of the proportion of the drug that is simply adsorbed (or anchored) at the external surface of the nanocarrier. The new porous hybrid solids, with the ability to tune their structures and porosities are well suited to serve as nanocarriers for delivery and imaging applications. Here we show that specific non-toxic porous iron(III) - based metal - organic frameworks with engineered cores and surfaces, as well as imaging properties, function as superior nanocarriers for efficient controlled delivery of antitumour and retroviral drugs against cancer and AIDS. They also potentially associate therapeutics and diagnostics, and open the way for theranostics, or -personalized patient treatments. double dagger.
