Upcycling fish scales for water pollution control and encryption 3 (IMAGE)
Caption
From left to right: Heat-treated fish scales, including some that have adsorbed the Rhodamine B pollutant, under white light, UV light and green light. Under green light, a hidden word "NUS" is formed from the fish scales that have adsorbed Rhodamine B. This underscores the scales’ potential as a material to convey concealed information.
