Rewrite the following paragraph using Active voice. 1. Argon lasers and household "Super Glue" are now used by some dactylography experts to collect fingerprints. A small, highly concentrated, single wavelength light beam is produced by the laser. Fluorescence is induced by the laser in such fingerprints chemicals as riboflavin. Prints -even old ones -- can be lifted from paper, something that has been impervious to traditional dusting, by the laser. The benefits of "Super Glue" were discovered by accident. The fumes from the glue interact with the amino acids and outline the print. A fingerprint is raised and preserved by "Super Glue" on just about any surface. The glue is used on smooth surface such as skin, plastic, coarse metal and leather.
