Importantly, the position of the plasmon band and its bandwidth

• ; organic fluorescent dyes; silica nanoparticles; stimulated emission depletion (STED) microscopy; Introduction With the emergence of nanotechnology, numerous applications have been developed using the size-related properties of nanoparticles [1][2]. In biomedical research, nanoparticles are applied as

• nanoparticles [24][25], silica nanoparticles [26] or quantum dots [27][28]. These fluorescent nanoparticles fulfil some of the specific requirements and overcome disadvantages of common organic fluorescent dyes [29]. Especially silica nanoparticles have proven useful, since silicon chemistry provides a
