Grafting functional groups on enamel surface by a self-assembled monolayer technique / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To study the influence of various active groups grafted on the enamel surface by means of self assembly on enamel biomineralization.</p><p><b>METHODS</b>The enamel was prepared by immersing the bicuspid tooth into 1 mmol/L ethanolic solution of a omega-functionalized (omega=PO4H2, SO3H, COOH or OH) group and deionized water solution of HSCH2CH2SO3Na for 24 h at room temperature. The contact angles and infrared (IR) images were used to identify the morphological changes of the enamel with chemisorption of the functional groups.</p><p><b>RESULTS</b>The contact angles and IR images showed that the omega-functionalized (omega=-PO4H2, -SO3H, -COOH, -OH or -CH3) group was chemisorbed on the enamel surface.</p><p><b>CONCLUSION</b>Self assembled monolayers with omega-functionalized (omega=-PO4H2, -SO3H, -COOH, -OH or -CH3) group can be successfully formed on the enamel surface by hydrolyzation.</p>
