Two-dimensional(2D) self-assembly of fine gold nanospheres using laser patterning

Self-assembled monolayers (SAMs) formed by the adsorption of alkanethiols, HS(CH2)nX, where X is an organic functional group, onto gold surfaces have attracted widespread interest as templates for the fabrication of molecular and biomolecular microstructures. Previously photopatterning has been thought of as being restricted to the micron scale, because of the well-known diffraction limit. So, we have explored a novel approach to nanofabrication by utilizing a femtosecond laser.
