Schematic of nanoparticles functionalized with agents that control their stability and interactions with the biological environment. A. Single-walled carbon nanotube (SWNT) tailored for vessel delivery of a therapeutic payload by coating the SWNT with polyethylene glycol (PEG) chains linked to arginine-glycine-aspartic acid (RGD), a potent αvβ3 integrin-binding peptide. B. Lipidoid nanoparticles that are formulated with phospholipids and cholesterol to facilitate intracellular delivery of siRNA for potent gene knockdown. Figures modified from [50] and [60].
