GREEN NANOTECHNOLOGY – IN KEY ENABLE TECHNOLOGIES – NEED OF ALL-BIO MATERIALS BIOPHOTONICS - BIOTRONICS • Biopolymers like deoxyribonucleic acid – DNA and collagen show very interesting properties as possible matrices for active molecules, being able to replace synthetic polymers. • These biopolymers are extracted from waste of food processing industry and their sources are practically unlimited. • Their degradation time is much faster than that of synthetic polymers in similar conditions. • Recently the scientists turn their attention to natural photosensitive materials, which can be extracted from flowers or fruits, like anthocyanines showing some photoresponsive properties for biophotonic applications.
DNA-Plant extracts
INTERCALATION OF GREEN TEA AND SEABUCKTHORN EXTRACT WITHIN DNA The aim of this research is: • To obtain new functional materials by using DNA-GTE / DNA-CTMA-SBE complexes for applications in photonics. • DNA is extracted from waste of food processing industry and its sources are practically unlimited. • Green tea is known as a very powerful antioxidant and antimicrobial agent, production is important in world, close to 700 000 tonnes in 2010 and is increasing. • The sea buckthorn berries are rich in vitamins, minerals and antioxidant components, including ascorbic acid, tocopherols, polyphenols and carotenoids.
Biodegradable compounds used Green tea plants Sea buckthorn berries
PERSPECTIVES – ALL-BIO MATERIALS BIOACTIVE MIXTURE WITH UNIQUE BIOTRONIC PROPERTIES - ANTHOCIANINS
Perspectives in Biophotonics • It is possible to obtain all-bio-functionalised DNA-based materials doped with natural extracts endowed with NLO properties. • The DNA-GTE complex exhibits UV excited photoluminescence, with higher intensity than for GTE alone, being a possible candidate for blue LED’s and blue lasers fabrication.
Natural extracts – source of biomolecules in pharmaceutics, cosmetics, nutraceuticals …
