Silica Particles with Encapsulated DNA and Magnetite as Hydrological Tracer: Magnetic Concentration and Proof-of-Concept

DNA has a number of characteristics which make it very promising as a hydrological tracer. It is detectable in extremely low quantities and can provide a virtually unlimited amount of unique tracers. The DNA tracer method has been further developed towards a multipurpose tracer combining a DNA tag, a paramagnetic core and a protective coating...
