Detecting iron the smart way

12 Nov 2013

Spanish scientists have developed a way to quantitatively measure the amount of iron in a solution using a colour changing material and photos taken on a smartphone.

Iron is present in almost every aspect of our lives but an excess, known as iron overload, can cause significant long term effects ranging from liver damage to arthritis as a result of iron deposition in organs or joints. As such, the amount of iron in a variety of environments needs to be carefully monitored.

Unlike traditional quantitative techniques, which require removing samples to the lab for assessment by trained specialists, the new approach devised by José Miguel García and colleagues at the University of Burgos can return a result within 15 minutes. Central to the technique is 8-hydroxyquinoline, a particularly stable iron chelator, which is immobilised on a polymer disk and will change colour depending on the amount of iron chelated to it.

Eye spy cyanide

03 Aug 2012

The colour of cyanide poisoning is purple, according to researchers in Switzerland who have developed a method that enables them to quickly detect blood cyanide levels through a simple colour change.

The two-step method to detect cyanide. (A) Adding a chemosensor to a blood sample, followed by extracting the purple chemosensor–cyano complex from the sample. (B) Washing the column with water

Cyanide poisoning as a result of smoke inhalation can have serious or fatal consequences unless an antidote is rapidly administered. Current methods for determining cyanide poisoning, including microdiffusion, microdistillation and liquid chromatography-mass spectrometry detection, can take up to an hour to give results and are not suitable for point-of-care settings.

Anion detection method to help police fight crime

01 Aug 2012

Chemical ignition Molotov cocktails consist of a flammable liquid and sulfuric acid and potassium chlorate in a glass bottle. The mixture is set alight by the reactants’ reaction on smashing the bottle

Researchers in Spain have developed a fast, non-hazardous method of identifying the anions present in improvised incendiary devices (a type of petrol bomb). This information will be important to police officers, as knowing the components of the original device could potentially help lead to the suspects involved.

Carmen García-Ruiz of the University of Alcalá, Madrid, and her co-workers studied a particular type of device – so-called chemical ignition Molotov cocktails (CIMCs), which consist of a flammable liquid (typically petrol) along with sulfuric acid and potassium chlorate in a glass bottle. Rather than needing to be lit by the thrower, the exothermic reaction of these ingredients on contact sets the mixture alight.
