      abstract     = {Advances with para-hydrogen induced polarization open up
                      new fields of applications for portable low-field NMR. Here
                      we report the possibility of tracing drugs down to the
                      micromolar regime. We could selectively polarize nicotine
                      quantities similar to those found in one cigarette. Also
                      less than 1 mg of harmine, a drug used for treatment of
                      Parkinson's disease, and morphine extracted from an opium
                      solution were detectable after polarization with
                      para-hydrogen in single-scan (1)H-experiments. Moreover, we
                      demonstrate the possibility to selectively enhance and
                      detect the (1)H-signal of drug molecules with PHIP in proton
                      rich standard solutions that would otherwise mask the (1)H
                      NMR signal of the drug.},
