Latest Patents
Jakob holds 3 patents related to the preparation of metal colloids. His latest patents describe a method for producing a silver colloid solution that results in highly stable colloids. The process involves adding an aqueous solution of a hydroxylamine salt to an aqueous solution of an alkali. Subsequently, an aqueous solution of metal ions is dispersed into the mixture. The hydroxylamine salt is selected to ensure that the anion forms a metal salt with very low solubility in water. The introduction of the metal ion solution is done in a manner that ensures the metal ions are substantially dispersed throughout the mixture within one second. A maturing period at elevated temperatures leads to a stable state, where the characteristics of the colloid undergo no further changes. It is preferred to store the colloid in a polystyrene container for optimal stability. The resulting colloids exhibit high light-scattering properties, small particle size, low background fluorescence levels, and a long shelf life, making them particularly suitable for Raman spectroscopy.
