Figure 1From: A promising gene delivery system developed from PEGylated MoS2 nanosheets for gene therapySynthesis and characterization of MoS 2 and MoS 2 -PEG. (a) A scheme showing the preparation of MoS2-PEG-PEI and the subsequent loading with siRNA. (b) AFM images of MoS2 before and after PEGylation. (c, d) AFM measured diameter (c) and thickness (d) distributions of MoS2 and MoS2-PEG. Over 100 nanosheets were counted for each sample.Back to article page
