The synthesis of bile acid oligodeoxynucleotide conjugates via the 3-OH group of the bile acids is described. When used in vivo in rats, covalent conjugation of an oligodeoxynucleotide via a linker to cholic acid resulted in an increased biliary excretion of bile acid-oligodeoxynucleotide conjugates compared to unconjugated oligodeoxynucleotides.
The emission of light in the blue-green region from cubic InxGa1-xN alloys grown by molecular beam epitaxy is observed at room temperature and 30 K. By using selective resonant Raman spectroscopy (RRS) we demonstrate that the emission is due to quantum confinement effects taking place in phase-separated In-rich quantum dots formed in the layers. RRS data show that the In content of the dots fluctuates across the volume of the layers. We find that dot size and alloy fluctuation determine the emission wavelengths.
