Sentences with phrase «np cluster size»

Not exact matches

Independent control and tuning of the fluence: each excitation laser pulse provides maximal flexibility in manipulating the lifetime (i.e. size) of the rainbow PNB in a wide range of cluster size and composition, thus circumventing the problem of the heterogeneous formation and content of NP clusters in cells.

The internalization and clustering of NPs in living cells (unlike the water model studied above), involves several biological processes that not only form such clusters, but also create significant heterogeneity in their size.

The size of NP clusters was quantified and compared through the amplitudes of their optical scattering images (obtained for individual NP clusters).

This mechanism works through the selective formation of NP clusters (tightly aggregated groups of 5 - 50 NPs) in specifically targeted cells and the cluster size - dependent mechanism of optical activation of such NP clusters through the generation of plasmonic nanobubbles (PNBs)[35 - 38].

PNB lifetime (ns)(measure of its maximal diameter) obtained for individual gold NP clusters of similar size for the different combinations of NP types and the wavelengths of optical excitation (@optical fluence, mJ / cm2).
