• clathrin-dependent pathways. In agreement with our results, other studies also showed that clathrin-dependent uptake plays an important role in the internalization of nanoparticles, e.g., silver NPs (diameter: 50 nm) [42] and polystyrene NPS (diameter: 40 nm) [43]. The presence of dynasore also reduced the

• nanoparticles directly into the liquid [79]. Although the phase matching condition was not fulfilled, the average particle spacing had been adjusted such as to be smaller than the coherence length, while the pump wavelength was matching the localized surface plasmon resonance of the silver NPs. In this first

• hydrodynamic radius of 57 nm and 69 nm for the aggregate component. As these sizes are not superposed by the scattering signal of proteins, this observation gives evidence of a reduced diameter for the samples PEG@POS-NH2Q1 and PEG@POS-NH2Q2 in presence of proteins. For silver NPs, an additional sterical

• this problem. Stepanov et al. [22] have shown that the implantation of 60 keV Ag ions with fluences of (2–4) × 1016 ions/cm2 leads to the formation of silver NPs in glass near room temperature. It has been shown that Au atoms get buried [10] during the ion beam irradiation of thin films. Ion beam
