Fig. 3: Morphology of ESi5-S agg.
From: A stable and biocompatible shortwave infrared nanoribbon for dual-channel in vivo imaging
The TEM image (a) and the Cryo-EM image (b) of ESi5-S agg (200 μM) in H2O. c The AFM image of ESi5-S agg with cross-section analyses (d) along red dashed lines. The dark spots are crystalline ice. Each experiment was repeated independently with similar results (n = 3).
