Self-assembled monolayers have been the workhorse for nanotechnology since a few decades. They constitute an interface and �interphase� between a substrate and the �outside world�. Their functions have progressed into ever increasing added value including molecular recognition, molecular construction, biomolecular orientation, electronic transport, signalling, etc.Reactive monolayers, i.e. monolayers that have some reactive moiety at the headgroup that allows further functionalization, form a subclass that is extremely useful for molecular (nano)fabrication. The reactivity of such monolayers can be the same or drastically different than of their solution analogs.The current presentation focuses on examples that range from biomolecular templates to technological applications. The development of reactive platforms that signal attachment reactions occurring onto them is useful for biomolecular arrays. Examples will be shown of protein patterns, using a thiol-reactive platform. Surface gradients are being developed and used to address and map reactivity profiles on surfaces on reactive monolayers.
