Porous Glass Electrophoresis

Fluorescent Nanomaterials for the Development of Latent Fingerprints in Forensic Sciences

“…In 1961, MacDonell et al first reported the use of magnetic powders for latent fingerprint development. [17] Fluorescent powders were introduced for latent fingerprint development in the late 20th century, after the laser was used for visualizing latent fingerprints. In 1977, coumarin-6 was first employed as a fluorescent powder for developing the latent fingerprints along with the use of an argon ion laser.…”

Electrochromatography

“…Cellulose acetate is preferred over paper not only because of its greater resolving power but also because its transparency facilitates densitometry (1, 27, 68, 70). Other media that have been proposed for separating small amounts of mixtures include thin films of kieselguhr (79), asbestos paper for electrochromatography in fused salts (2, 4, 100), and a special form of porous glass (104). A cellulose fiber has been used to separate submicrogram amounts of nucleic acids in tissue extracts (49).…”

Characterization of Fountain Pen Inks by Porous Glass Chromatography and Electrophoresis

“…In addition, the final separations would be in a medium which was itself optically transparent. This unique glass was obtained and found to be quite acceptable for these applications (24)(25) (26). Inasmuch as porous glass is a medium unknown to many readers perhaps a brief description of its properties should be included at this time.…”
