Laser scanning confocal microscopy (LSCM) confirmed the successful functionalization of silicon oxide microchips attached to the surface (Figure ) with either Bdpy1 (λex = 488 nm, λem = 498-531 nm selected according to emission Bdpy1 spectrum) or Bdpy2 (λex = 590 nm, λem = 595-630 nm selected according to emission Bdpy2 spectrum). Whereas non-functionalized silicon oxide microchips (SOµC) attached to the surface showed no fluorescence emission (Figure ), both functionalized microchips SOµC-Bdpy1 and SOµC-Bdpy2 still attached to the surface exhibited strong fluorescence emission (Figure and), which is clearly reflected by their fluorescence intensity profiles as well as 3D diagrams (Figure ).
