Analytical and Bioanalytical Chemistry v. Anti-doping analysis by Benfluorex fdating Thevis His research interests include the development of methods targeting non-approved emerging drugs with potential for misuse in sport, elucidation of metabolic pathways of drug candidates, and, particularly, the identification of peptidic drugs and their metabolites in blood and urine.

He has published over articles in peer-reviewed international journals, authored a book on mass spectrometry in sports drug testing, received the Manfred—Donike and Beynon—Price awards, and is Editor-in-Chief of Drug Testing and Analysis. Doping analysis relies on the determination of prohibited substances that should not be present in the body "Benfluorex fdating" an athlete or that should Benfluorex fdating below a threshold value.

In the case of xenobiotics their mere presence is sufficient to establish a doping offence. However, in the case of human biotics the analytical method faces the difficulty of distinguishing between endogenous and exogenous origin. For this purpose ingenious strategies have been implemented, often aided by state-of-the-art technological advancements such as mass spectrometry in all its possible forms.

For larger molecules, i. Although approaches these confer specificity and sensitivity to the applications, most rely on the use of two, or even three, antibody incubations with the consequent increment in assay variability.

Moreover, the requirement for different antibodies Benfluorex fdating separately recognise different epitopes in screening and confirmation assays further contributes to differences encountered in either measurement.

The development of analytical techniques to measure interactions directly, such as atomic force microscopy, quartz crystal microbalance Benfluorex fdating surface plasmon resonance, have greatly contributed to the accurate evaluation of molecular interactions in all fields of biology, and expectations are that this will only increase.

Here, an overview is provided of surface plasmon resonance, and its particular value in application to the field of doping analysis.
