We use high-resolution techniques such as confocal fluorescence microscopy for the investigation of energy-transfer processes. The experiments are supported by simulations of the electromagnetic field enhancement in

Prior to the two-step functionalization with APTES and FITC, the quality of the silane layer formation is tested and proven by the binding of long-chained silanes, which are known to form densely

FITC functionalized nanostructures have been investigated using fluorescence microscopy, which further confirms

By using a dual atomic force microscope (AFM) and confocal microscopy setup, diamond nanocrystals that contain single color centers are then identified by fluorescence microscopy and second-order photon autocorrelation, and their position

Again, the fluorescence microscopy image (Figure 8c) supports the notion that the darker areas in Figure 8a are in fact arrays of rectangles formed by the [Zn2(adc)2(dabco

Fluorophores are not merely position markers, but can be regarded as active transducers that interact with species in their local vicinity and provide information about their micro-environment.
