From: Understanding the mechanism of Nb-MXene bioremediation with green microalgae

Stimulation (+) or inhibition (−) of microalgal growth in the presence of SL (a) Nb2CTx and (b) Nb4C3Tx MXenes. The analysis was performed for 24, 48 and 72 h of MXene-microalgae interaction. Significant data (t-test, p < 0.05) were marked with an asterisk (*). The red arrows indicate the reversal inhibition-to-stimulation effect.
