Industrial scale production, coupled with unique material properties, underpin rising concerns of engineered, nanoscale materials inadvertently affecting the health and function of natural systems. Conversely, novel material properties may be utilized to uniquely address current environmental issues. Key to the 'nano-envi' paradigm is the fundamental understanding of the material(s) interfacial behaviors in both natural and engineered systems. I will discuss both sides of the issue, using two model systems as examples. Regarding implications, the behavior of a relevant, functionalized series (serially altered) of water soluble fullerene derivatives will presented covering a matrix of environmental surfaces, water chemistries and reactions. Partitioning/sorption processes as a function of surface derivatization (type and frequency) will be detailed. Second, low-level metal sensing applications of monodispersed, superparamagnetic nanoscale iron-oxides, will be discussed as a function of surface coating(s) / stabilization chemistries.
