Microcontact Printing of an Alkylsilane Monolayer on the Surface of Glass

This paper describes the use of microcontact printing (/LCP) for patterning of self- assembled monolayers (SAMs) of (3-ami nopropyl )- t riethoxysilane (APTES) and octadecylrichloro silane (OT S) on the surface of glass and functionalization of alkylsilane monolayers, After activation of the glass surface, which was patterned with OTS using a poly (dimethylsi loxane) (PDlvIS) stamp , the remaining bars of the surfaces were treated with APTES and then treated with a dye solution. The characterization of printed silane compounds was confirmed using Auor escence microscopy on the basis of the reaction between terminal amine groups of APTES and thionylchloride of Rhodamine -B dye. Quant it ative 3dimensional profiling was performed for the whole modification process by converting of microscopic images to numerical dimensions .
