We present a new family of fluorescent probes with varying emission colors for selectively imaging hydrogen peroxide (H 2 O 2 ) generated at physiological cell signaling levels. This structurally homologous series of fluorescein-and rhodol-based reporters relies on a chemospecific boronate-tophenol switch to respond to H 2 O 2 over a panel of biologically relevant reactive oxygen species (ROS) with tunable excitation and emission maxima and sensitivity to endogenously produced H 2 O 2 signals, as shown by studies in RAW 264.7 macrophages during the phagocytic respiratory burst and A431 cells in response to EGF stimulation. We further demonstrate the utility of these reagents in multicolor imaging experiments by using one of the new H 2 O 2 -specific probes, Peroxy Orange 1 (PO1), in conjunction with the green-fluorescent highly reactive oxygen species (hROS) probe, APF. This dual-probe approach allows for selective discrimination between changes in H 2 O 2 and hypochlorous acid (HOCl) levels in live RAW 264.7 macrophages. Moreover, when macrophages labeled with both PO1 and APF were stimulated to induce an immune response, we discovered three distinct types of phagosomes: those that generated mainly hROS, those that produced mainly H 2 O 2 , and those that possessed both types of ROS. The ability to monitor multiple ROS fluxes simultaneously using a palette of different colored fluorescent probes opens new opporunities to disentangle the complex contributions of oxidation biology to living systems by molecular imaging.

“…The bond configuration of synthesized CdTe nanostructures is shown in Figure 4. As can be seen for CdTe-EDA nanowires (Figure 4) the following bands obtained: The band appeared at 879 cm -1 can be allocated to stretching vibration of N-H and C=N bonds, respectively [25]. The C-H stretching vibration groups were seen at various wavenumbers, being around 1384 cm -1 10) nanorods with an average diameter of 150 nm are shown in Figure 2c.…”

One dimensional Cadmium Telluride (CdTe) with different morphology was successfully synthesized via a solvothermal process by controlling the nature of precursors and solvents at a moderate temperature of 180 °C. X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy analyses revealed that in all cases highly pure and crystallized CdTe with cubic zinc blende structure were obtained. Field emission scanning electron microscope (FE-SEM) analysis revealed that high aspect ratio CdTe nanowires, CdTe nanobelts, and CdTe nanorods were obtained in the presence of ethylenediamine, ethanolamine, and triethylenetetramine, respectively. Also, it was found that the solvents influence on the morphology of CdTe nanostructures. UV-Vis absorption spectra of CdTe nanostructures prepared under different conditions exhibited a blue shift relative to that of bulk CdTe due to the quantum size effect.
