Following previous studies with a DOTA-like bifunctional chelator (H(3)L1) containing an ethylenic linker between the macrocycle backbone and a quinazoline pharmacophore, we synthesized and fully characterized a congener macrocyclic ligand (H(3)L2) having a longer, five-carbon spacer for the linkage of the quinazoline moiety. Both H(3)L1 and H(3)L2 were used to prepare indium(III) complexes aim...
This study aims to characterize phosphate buffer and urease enzymes through the absorbance spectrum of UV-Vis FTIR using tungsten as indicator electrode. The method used in this research is biosensor potentiometric carried out Laboratory Faculty Mathematics Natural Sciences, State University Medan Beacukai Belawan laboratory. characterization electrolyte solutions various compositions showed th...
The C-3 phenolic hydroxy group containing morphine derivatives (morphine, oxymorphone, naloxone, naltrexone) are excellent candidates for the synthesis of 3-O-functionalized molecules. Achieving free carboxylic gives opportunity further modification and conjugation that could be used immunization immunoassays. For this purpose ethyl bromo- chloroacetate can as O-alkylating agents. Hydrolyzing p...
We fabricate α-terthiophene single-molecule junctions (SMJs) and characterize their conductive states by the simultaneous measurements of surface-enhanced Raman scattering (SERS) electronic conductance. The SMJ showed broad conductance distribution due to different portions multiple aromatic rings connected electrodes. SERS spectra obtained measurement vibrational energy C−C stretching mode dep...
