Aggregation kinetics. (A) SPT shows aggregation extractions of total SWCNTs from solution. (B) Approximating total SWCNT volume through 8 h of aggregation at 37 °C shows significant SWCNT extraction. (C) Comparison of protein concentration through BCA assay for two media types. (D) Amount of free protein postaggregation as a function of SWCNT concentration for conditioned media.
