A female stimulation device comprising a resilient device body having a partially deformable tip portion, a flange and an intermediate side wall portion extending outwardly from the tip portion to the flange. In one embodiment, a method includes providing a semiconductor substrate and forming a metal silicide on the semiconductor substrate. The apparatus for multi-batch production of FDG includes a reagent delivery system, a reaction vessel, a filter assembly, and a control system. The two or more sets of information about the mark preferably vary from each other in time, spacedirectionality, color, frequency or any combinations thereof, and can be captured or acquired as part of one, two, or more images of the microparticle mark. Methods of making the compounds, compositions including the compounds and methods of treatment of conditions involving reactive oxygen species are also provided.
