Alternative methods proposed to detect pesticides and antibiotics in water and natural food

09-18-2007 · EurekAlert!

Research by the department of analytical chemistry at the UGR has developed new systems to achieve sensitive detection of pesticide and antibiotic residues in water, vegetables, milk and meat using innovative techniques. Presence of antibiotics in foods of animal origin or fresh water can cause bacterial resistance or allergic reactions, as well as industrial problems in fermentation processes.

A new portable biosensor detects traces of contaminants in food more quickly and cheaply
05-17-2007 · EurekAlert!
Scientists at the Universitat Autònoma de Barcelona and the CSIC, have developed a new electrochemical biosensor which detects the presence of herbicides as well as antibiotics in food. The biosensor is faster, more portable and economic than usual laboratory methods, while having a similar sensitivity. The system has been tested successfully to detect pesticides in samples of drinking water and commercial orange juice, as well as to detect traces of antibiotics in cow's milk.

Animal testing alternative has ticks trembling at the knees
11-05-2006 · EurekAlert!
Scientists in Switzerland have developed a synthetic cowhide as a replacement for live animals when observing the effects of new anti-tick treatments. Traditional testing methods for these agents involve coating animals in harsh chemicals, and measuring how quickly ticks die. The new animal friendly method is also far more sensitive, and effects can be measured sooner by observing "leg trembling" -- an early symptom of the pesticide blocking the tick's central nervous system.

Alternative Energy: New Way To Take A Bite Of Sunlight
10-05-2006 · ScienceDaily
Flash those pearly whites in a dazzling smile and you showcase a natural light collector mechanism hidden inside the internal structure of dentin - the hard, bone-like material that forms the main part of teeth. Scientists in Germany are reporting that the photonic crystal structure of dentin was their inspiration to propose a new method for harvesting sunlight to produce electricity.

Photodynamic therapy as alternative therapy for periodontal diseases may be beneficial
03-06-2007 · EurekAlert!
Photodynamic therapy (PDT) may be an effective way to treat the bacteria associated with periodontal diseases, and could provide a better option than antibiotics or other mechanical methods for treating periodontal diseases, according to a new study published in the March issue of the Journal of Periodontology.

100 percent of pregnant women have at least one kind of pesticide in their placenta
05-14-2007 · EurekAlert!
A doctoral thesis written at the Department of Radiology and Physical Medicine of the University of Granada reveals an average presence of eight organochlorine contaminants in the organisms of pregnant women, which are usually ingested by means of food, water and air. These chemical substances may cause some malformations in the genito-urinary system of the foetus, such as cryptorchidism and hypospadias.

Gold nanoparticles help detect a toxic metal -- mercury
04-27-2007 · EurekAlert!
With gold nanoparticles, DNA and smart chemistry as their tools, scientists at Northwestern University have developed a simple "litmus test" for mercury that eventually could be used for on-the-spot environmental monitoring of bodies of water, such as rivers, streams, lakes and oceans, to evaluate their safety as food and drinking water sources. An article detailing the technology's success will be published online April 27 by Angewandte Chemie, the prestigious European journal of applied chemistry.

New technique developed for tracking cells in the body
03-20-2007 · EurekAlert!
Scientists' inability to follow the whereabouts of cells injected into the human body has long been a major drawback in developing effective medical therapies. Now, researchers at Johns Hopkins have developed a promising new technique for noninvasively tracking where living cells go after they are put into the body. The new technique, which uses genetically encoded cells producing a natural contrast that can be viewed using magnetic resonance imaging (MRI), appears much more effective than present methods used to detect injected biomaterials.
