From: Fabrication of fluorescent nanospheres by heating PEGylated tetratyrosine nanofibers
Selected SEM micrographs for self-assembled PEG6-Y4 nanostructures drop-casted after heating in stove for 4 h and re-dissolved in MeOH (a), H2O/MeOH (50/50, v/v) (b) and H2O/MeOH (0.025/99.75, v/v) (c). Magnification and scale bar for all the samples are 12,0000×, 1 µm.
