From: Understanding the mechanism of Nb-MXene bioremediation with green microalgae
SEM images showing surface interactions between green microalgae and MXene nanosheets after 72 h of interaction with extreme concentration (100 mg L−1). (a) Untreated green microalgae, and after interaction with SL (b) Nb2CTx and (c) Nb4C3Tx MXenes. Note that Nb-MXene nanoflakes are marked with red arrows. For comparison purposes, photos from a light microscope have been also added.
