plasma technology to fight faking wins uk engineering award anticounterfeit technology

dr matthew murray created alpin, a patented technology that allows anticounterfeiting plasms to be implanted into glass, creating a pattern on the syrface that can be used to identify individual batches of products in bottles, such as pharmaceuticals, alcohol and perfume. this is done by implanting any glass with femtosecond laser generted plasma a highly charged and energetic gas, such as one containing optically active elements. this introduces visible or lightactivated colouring 9e.g. when exposed to uv toa glass. applying a mask, analogous to a stencil, ultrafast laser plasma implantation ulpi can create a pattern upon the surface, such as a barcoder or branding.
