The Molecular and Cellular Mechanisms for Nanoparticle Transport
… is to deliver drugs to the tumour using nanoparticles. However, this tumour delivery is not an efficient process. Less than 1% of nanoparticles injected into the blood will reach the tumour while the rest of nanoparticles accumulate in off-target tissues. To improve tumour delivery, it is …

Nanoparticle Transport Through Fractures And Heterogeneous Porous Media
Nanoparticles have a diffusion constant a couple of orders of magnitude smaller than inert chemical tracers such as potassium bromide (KBr), and this means that they can potentially be used to measure the degree to which subsurface flow occurs through fractures and high permeable zones in …
