Abstract
A method of stabilizing riboflavin by affixing the riboflavin to at least one substrate for the riboflavin by covalent bonding, hydrogen bonding, Van der Waals forces, or a combination thereof, to form an optically-activated complex, is provided. When activated by absorption of light in the ultraviolet (UV) to visible region of the electromagnetic spectrum the riboflavin in the complex re-emits light of longer wavelength in the blue-green-yellow region of the electromagnetic spectrum.
Claims7
A method of stabilizing riboflavin against degradation upon exposure to UV light by (a) mixing a hyaluronic acid substrate with a solution of riboflavin, and (b) evaporating the liquid to form an optically-activated complex in the form of a gel that will absorb light in the wavelength range of 260 to 460 nm and emit light in the wavelength range of 470 to 650 nm.
