The invention relates to self-assembled organosilane coatings for resorbable medical implant devices. The coatings can be prepared from coating compositions containing organosilane and can be applied to metal or metal alloy substrates. Prior to applying the coatings, the surfaces of the substrates can be pretreated. The coatings can be functionalized with a binding compound that is coupled with an active component. The coatings can be selectively removed, e.g., patterned, to expose portions of the uncoated substrate. Selecting different patterns can provide the ability to regulate or control various properties, such as, corrosion and hydrogen generation.
