Abstract

Raman and infrared spectra of two types of disposable soft contact lenses are presented and discussed in order to correlate the chemical structures of the polymers to bacterial adhesion on their surface. The results of the adhesion study show that Staphylococcus aureus adheres better to more hydrophilic lenses. The spectroscopic results point out that the different chemical structures of the polymers can explain not only the different water amounts in the lenses, but also play an important role on the adhesion capability of Staphylococcus aureus.
