A method for functionalizing a surface of a dielectric plate that is transparent to visible light&#x2014;to be able to examine the dielectric plate using optical microscopy&#x2014;includes depositing a negative film on the dielectric slide. The negative film comprises a polymerizable composition that polymerizes when exposed to an electron beam. The polymerizable composition is polymerized&#x2014;by exposing the negative film to the electronic beam&#x2014;at a set of points representing a preset pattern. Non-polymerized portions of the polymerizable composition are dissolved&#x2014;to develop the negative film&#x2014;forming a set of pads of polymerized portions of the polymerizable composition. Each pad corresponds to one point of the preset pattern. A metal film is disposed on the negative film, and the developed negative film is dissolved to define holes through the metal film. Each of the holes corresponds to a base of one pad of the set of pads.
