The encapsulation of magnetic nickel nanowires (NiNWs) with gelatin is proposed as an alternative for optical label detection. Magnetic nanowires can be detected at very low concentrations using light-scattering methods. This detection capacity could

Here, we describe a method to measure turbidity in liquids by probing a graphic pattern by optical transmission. Data are collected by a video camera, and a mathematical algorithm is used to correlate image loss with turbidity. We report high-resolut

A method is proposed to impregnate regular cellulosic paper with semi-conductive particles of copper sulfide. The method consists of a simple two-step procedure: first, metal (Cu) ions in solution are applied to the paper, and second, the aqueous app
