If agricultural plants are exposed to carbon nanotubes (CNTs), they can potentially take up CNTs from the growing media and translocate them to different tissues. In addition, agricultural application of CNTs recently attracted increasing attention, as they could promote germination, enhance crop yield, and exert other benefits. For evaluating the environmental effects of CNTs and optimizing their agricultural application, it is essential to quantify CNTs in plant tissues.  We have developed several different methods including Raman, thermal analysis, and spectroscopic analysis coupled with digestion for analyzing pristine (p-) and carboxyl functionalized (c-) multiwall CNTs (MWCNTs) in plant (lettuce) tissues. These methods have been applied for measuring CNTs concentration in lettuce grown hydroponically with CNTs in culture solution. These methods can also be potentially applied to other carbonaceous nanomaterials in complex environmental media.<br/>
