ROS scavenging and anti-inflammatory properties of MoS2/GO/PVA hydrogel. a The effect of PVA (set as control), GO/PVA, MoS2/PVA, and MoS2/GO/PVA hydrogels on ROS production in H2O2-induced NE-4C cells. Scale bar = 50 μm. b DCF fluorescence intensity of PVA (set as control), GO/PVA, MoS2/PVA, and MoS2/GO/PVA hydrogels. c The M1, M2 macrophage ratio in each group. d The flow cytometry images of RAW264.7 cells after cultured with PVA (set as control), GO/PVA, MoS2/PVA, and MoS2/GO/PVA hydrogels for 24 h. e RT-PCR results of IL-6, IL-10, and TNF-α in different treatment groups; *p < 0.05. **p < 0.01. All groups were compared with the control group
