Antibacterial plaster could put a clean sheen on walls

February 11, 2009

Scientists in China are reporting development and testing of new self-sanitizing plaster with more powerful antibacterial effects than penicillin. The material could be used in wall coatings, paints, art works and other products. The study is in the current issue of ACS’ Crystal Growth & Design.

Liang-jie Yuan and colleagues note that plaster has been used for centuries as building material and surfaces for great works of art, including Michelangelo’s famed Sistine Chapel ceiling in Vatican City. The new, first-of-its kind plaster —formed from different ingredients from traditional gypsum plaster — still retains similar mechanical properties while having added antibacterial effects.

Lab tests showed that the so-called “supramolecular” plaster has a “very broad” antibacterial spectrum, killing five types of disease-causing bacteria. When compared with penicillin, the plaster was more effective at controlling growth of four kinds of bacteria, including dangerous Staphylococcus aureus and Escherichia coli. “It can be expected that the supramolecular plaster can be used for building, painting, coating and carving, and the coat, brick, or art ware constructed by the plaster do not need additive antiseptic or sterilization,” the authors say.
