摘要: Carbon nanotubes (CNTs) are a family of all-carbon quasi one-dimensional nanomaterials that highly hydrophobic and typically aggregated in bundles. Recent accomplishments dispersing CNTs aqueous solutions open possibilities for their new applications biomedicine. In many occasions, biological biomedical demand an actuation mechanism; thus, it is desirable to control the dispersion aggregation with external stimuli. Here, we report two "smart" single-walled CNT (SWNT) dispersions respond temperature pH changes through environment-responsive polymers, poly (N-isopropylacrylamide) (PNIPAAm) Poly-L-lysine (PLL).
