Drug test system detects substances that allow to control pulse in precision sports, such as motor racing

22.08.2006
The fight against drugs if the different sport disciplines is one of the main objectives of the International Olympic Committee (IOC), to which the group ‘Analytical, environmental, biochemical and food control’ of the Department of Analytical Chemistry of the University of Granada has contributed.

The researchers, directed by professors Alberto Fernández Gutiérrez and Antonio Segura Carretero, have designed an optical sensor that allows to determine the presence of propanolol (a beta inhibitor used as a performance-enhancing drug in the so-called precision sports, such as motor racing or archery) in urine.

The main contribution of their research work lies in the precision of this new system, cheaper, more accurate and, above all, faster that the old ones, as it can detect the presence of propanolol in just a few minutes, with an accuracy of 0.2 micrograms per litre.

Beta inhibitors are medicines that regulate the heart pace, slow down the cardiac frequency and stimulate the attention. They cause a reduction and improvement of pulse (reducing trembling), and they also have an anti-stress effect. Some of its undesirable effects are a sensation of permanent fatigue, a drop in arterial tension, muscular cramps, risk of psychical depression and sexual impotence if habitually and repeatedly consumed. Besides propanolol, other beta inhibitors are acebutonol, alprenolol, atenolol, labetalol, metoprolol, nadolol, oxprenolol and sotalol.

Their consumption has been banned by the IOC in precision sports such as chess, motor racing, billiards, bowling, air sports, winter sports (‘freestyle aerials’/’half-pipe’ jumping, ‘snowboard’ and ‘halfpipe/big air’), gymnastics, wrestling, motorcycling, pétanque, modern pentathlon, archery, ‘curling’ and sailing.

The ‘antidopping’ system designed by the scientists of the UGR [http://www.ugr.es] is part of the doctoral thesis ‘Development of fluorescent optosensors for the determination of pharmacological active principles and environmental pollutants in real samples’ [http://www.mcu.es/cgi-bin/TESEO/BRSCGI?CMD=VERDOC&BASE=TSEO&DOCN=000093558], carries out by Jorge F. Fernández Sánchez, another member of the research group which at present keeps on working on this research line.

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
