The coupling of an enzyme immunoassay with a superheated water extraction is an attractive technique because of the reduced use of hazardous solvents, due to their hostile impact on the environment. This paper describes the use of superheated water extraction and enzyme immunoassay (EIA) for the determination of polycyclic aromatic hydrocarbons (PAHs) in(More)
Scanning electron microscope images show that it is easy to generate nanopores on polycarbonate membranes with well-defined pore diameters by ion-track perforation and subsequent magnetron sputtering with metal. The size reduction of the nanopores during sputtering with gold is a linear function of time. Images of different angles and from the bottom side(More)
