This research will address critical issues related to the complete cycle of nanoparticles within biosystems. To predict how readily nanoparticles may enter biological tissues requires an unambiguous knowledge of particle dimensions and surface functionality. We will develop dimensional metrology to obtain precise structural information on nanoparticles combined with image enhancing simulations, and we will develop surface chemical characterization methods with atomic resolution. To reliably predict the state of nanoparticles inside biological tissues requires detailed knowledge of their dispersion and aggregation properties in biological fluids, for which we will develop x-ray scattering and associated metrologies. To estimate the probability of retention and removal of nanoparticles from biosystems requires knowledge of chemical interactions and transport properties of nanoparticles within and across biological tissues. We will develop nanometer-resolution neutron reflection for differentiating nanoparticle diffusion across biomembranes and simulated tissues. Modeling and simulation will generalize the fundamental properties of nanoparticles in biosystems. Through this effort, we will deliver critical support to other agencies such as NIH and EPA engaged in determining toxicology effects of nanoparticles in living organisms.
