Description General description Silver is a noble metal, extensively used in SERS, photocatalysis and solar cells. The surface of silver can be functionalized to attain specific properties such as biocompatibility and vapor selectivity of sensors.3 Iodized silver foils and thin films find potential use as SERS-active metal substrates.1 Cu substrates laminated with Ag foils, have compatible coefficient of thermal expansion (CTE), to be used for electronic packaging. Porous ZnO nanoplates deposited on silver foil with tunable hydrophobicity may be fabricated.3 Packaging 1 ea in rigid mailer Quantity 25 × 25 mm (approximately 6.6 g)
