New Tannic Acid and Iron Nano-Coating Cheap and Safe
As per reports, a new coating for drugs created by the researchers for is made from tannic acid and iron.
Published in the journal Science, the research suggested that the newly developed coating can act as a cheap and safe alternative to the existing drug delivery capsules and protective coatings. The revolutionary coating has been developed by a team led by Professor Frank Caruso, of the University of Melbourne.
Caruso said that the new coating is developed from the materials occurring naturally. It is not expensive and is safe for consumption, he added. The coating is said to be developed from self-assembling nano-materials.
It is learnt that such materials are now increasingly being used for making wide range of products including nano-capsules and anti-corrosive coatings.
Tannic acid used in manufacture is also used for dyeing cotton and preventing iron and steel corrosion. It also has application as an additive in drinks. The substance is mixed with iron in presence of substrate to form very thin coatings on these materials.
The thickness of the coat is said to be a few nanometers. "It's a form of nano-assembly. We see this as alternative strategy for delivering, for example, vaccines or therapeutics", says Caruso. It is considered to be safe and biologically friendly.
