Patents
The present invention relates to a hybrid organic-inorganic composite film. The invention also relates to a method for the manufacture of a hybrid organic - inorganic composite film useful for glucose sensing in aqueous solutions by observing colour change in the film and a method of glucose sensing using such novel film. A hybrid organic - inorganic composite film comprising gold ions selected from cationic and anionic forms of gold diffused in a lipid film comprising a lipid selected from the group consisting of fatty acids, fatty amines, fatty alcohols and phospholipids with a hydrocarbon chain length of 12 to 22 carbon atoms deposited on a substrate selected from the group consisting of glass, quartz and transparent polymer.
