(a) In vivo photoacoustic imaging of CNTs conjugated with ICG demonstrate high sensitivity. The PA signal increases linearly with CNT concentration.203 (b) Schematic of different CNT functionalization methods for therapeutic delivery: (1) covalent sidewall functionalization, (2) non-covalent adsorption, (3) entrapment, (4) non-covalent wrapping, (5) defect-group functionalization.69 (c) Depiction of irradiation effects in conjunction with CNTs and gold nanoparticles. CNTs incubated with MSCs and irradiated showed the biggest increase in ALP production. CNTs and gold nanoparticles adjacent to MSCs and irradiated showed more ALP production over controls without particles, but also irradiated.58
