• . This resembles the multi-photon detection [6], where for a smaller bias current (I = 23 nA), the slope is larger, ca. A·exp(−3bV), than for larger bias current, ca. A·exp(−2bV) for I = 25 nA and ca. A·exp(−bV) for I = 26 nA. Although we see a consistent switching due to 9 GHz signal even at 23 nA, at

Keywords: bioimaging (CT; MRI; Multi-photon); hetero-nanoparticles; Janus particles; protein corona; synthesis; Introduction In the recent years, there has been an increasing interest in design

• ]. Moreover, Au nanorods as well as Au@MnO@SiO2 Janus particles were shown to emit strong photoluminescence under two photon excitation used for in vitro imaging (Figure 14) [39][92]. In comparison to conventional microscopy, multi-photon microcopy is superior regarding the reduced fluorescence background

• laser power density of approx. 1 W·cm−2 was 1015 times smaller than that associated with multi-photon processes using ultra-short pulse (femtosecond) lasers [35]. Therefore, the DPP etching process cannot be attributed to conventional multi-photon excitation processes [36]. A comparison of atomic force
