Figure Lengend Snippet: Electrospun nanofibers and nanorods from macroscopic to nanoscopic scale. (A) Samples of fiber mats obtained in 35 mm dishes under white light (B) Samples of fiber mats obtained in 35 mm dishes under UV lamp (365 nm) (C) Fiber mat loaded with R18 dye during electrospinning process. Cylindrical collector is 20 cm length with 10 cm diameter. (D,E) Respective epifluorescence images of BlueCy/PtOEP and R18/Pt‐TPTBP fibermats with 2× objective (scale bar 1 mm). Insert show higher magnification with 60x objective (scale bar 50 µm). (F,G) TEM micrographs of BlueCy/PtOEP (F) and R18/Pt‐TPTBP (G) nanorods. (H,I) Scale bar: 500 nm. Diameter distribution of BlueCy/PtOEP (H) and R18/Pt‐TPTBP (I) nanorods measured from TEM images.
Article Snippet: Microscopy imaging was performed with a Nikon Ti‐E inverted epi‐fluorescence microscope, equipped with following objectives: CFI Plan Apochromat Lambda D 2X (NA = 0.1), CFI Plan Fluor 10X (NA = 0.3), CFI Plan Apochromat Lambda D 20X (NA = 0.75), CFI Plan Apo × 60 oil (NA = 1.4), CFI Apo TIRF 100XC Oil (NA = 1.49) and a Hamamatsu Orca Flash 4 sCMOS camera.
