Abstract
An attempt has been made to incorporate intercalation power of metal-flavonoids (metal-Fls) into ds.DNA for selective accumulation of heavy metal ions on DNA trapping water insoluble (3-aminopropyl)triethoxysilane (APTES) films. Three flavonoids (Fls) namely primuletin (prim), morin (mor) and quercetin (quer) were used to chelate heavy metal ions alone and through calf thymus DNA intercalation. Metal ion (M = Cu2+, Fe3+, Cr3+, As2+, Hg2+, Pb2+, Cd2+, Sb5+) captured from 10
