✦ Synopsis
We present chemical modification of self assembled monolayers (SAMs) using electron and ion-beam lithographies. We used thiolated polyethylene oxide (PEO) SAMs on gold to fabricate chemically contrasting patterns at the nanoscale. Patterned surfaces were characterized by X-ray photoelectron spectroscopy (XPS), time of flight-secondary ion mass spectrometry (ToF-SIMS). Results showed a chemical modification of surfaces patterned by means of electron beam (e-beam) lithography and a removal of PEO SAMs on the areas treated with the ion beam. The chemical modification of PEO SAMs converted the nonfouling surfaces on fouling surfaces.

## Abstract We report the development of laser‐scanning lithography (LSL), which employs a laser‐scanning confocal microscope to pattern photoresists that can be utilized, for example, in the fabrication of masters for use in soft lithography. This convenient technique provides even exposure across
Isocyanatosilane-derived cations, (n = 1-4) were mass-selected and reacted with Ñuorinated self-Si(NCO) n ', assembled monolayer (F-SAM) surfaces at low collision energy ( AE 100 eV). Examination of the scattered products revealed a variety of reactions from simple Ñuorine atom abstraction (e.g. for
