title: A novel application of quaternary ammonium compounds as antibacterial hybrid coating on glass surfaces.
abstract: A hybrid coating is prepared on a glass surface by a sol-gel process using tetraethoxysilane (TEOS) and Q(4)N(+)-Si(OR)(3). Transparent coatings with smooth surfaces were investigated against both Gram-positive (Escherichia coli) and Gram-negative bacteria (Staphylococcus aureus). A rapid decrease of the count for both strains was observed within 72 h. A significant correlation has been observed between the concentration of Q(4)N(+)-Si(OR)(S) and the antibacterial activity which has been thoroughly investigated.
