Tuesday lab Read your notes and describe the work in your lab report. What is the purpose of this research? What are new and unanswered questions?

Self-Assembled Monolayers of Alkylsilanes Water has an important influence on the mechanism of silane monolayer formation. Alkylsilane SAM with different functionalities can be used to control the surface selectivity to localize adsorption of molecules with selected combinations of terminal groups.
