New Findings on Tetracyclines Described by Investigators at Southwest University

May 20, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- New research on Tetracyclines is the subject of a report. According to news reporting from Chongqing, People's Republic of China, by NewsRx journalists, research stated, "A dual-wavelength overlapping resonance Rayleigh scattering (DWO-RRS) method was developed and validated for highly sensitive and selective assay of doxycycline residues in several meat samples. The response signals were dependent on the specific multi-site coordination between lanthanum(III) and doxycycline (DOTC)."

The news correspondents obtained a quote from the research from Southwest University, "And La(III)-DOTC complex would further aggregate to form [La(III)-DOTC](n) nanoparticles, resulting in the occurrence of two new scattering peaks. Notably, with the addition of DOTC, the increments of both of these two wavelengths were proportional to the concentration of DOTC over the ranges of 3.9-4.0 x 10(3) nmol L-1 (1.7-1.8 x 10(3) mu g/kg), The detection limit of DWO-RRS was 1.1 nmol L-1 (0.5 mu g/kg), which was lower than or comparable to most of the published methods."

According to the news reporters, the research concluded: "Additionally, the generating mechanisms of multi-response RRS signals were discussed and a semi-empirical principle was established for better design of multi-response RRS probes."
