Monitoring kidney disease on a smart phone

17-Sep-2013 - Researchers in the United States have developed a hand-held ‘albumin tester’ integrated with a smart phone for diagnosing and monitoring kidney disease. The lightweight device measures albumin levels in urine. The system, which could be used by kidney disease patients at home, integrates an ...

Artificial tongue made from polymer gel

15-Feb-2013 - Scientists in China have made polymer gels that behave like artificial tongues. By measuring how the gels swell, bend and fluorescence, the researchers found that the gels selectively respond to and can distinguish between sourness (citric acid and gluconic acid), sweetness (glucose), saltiness ...

A tattoo to monitor health

25-Nov-2010 - A sensor to be injected into the skin just like a tattoo that measures sodium concentrations in the blood has been developed by US scientists. The sensor could be used to monitor diseases or warn against dangerously low sodium levels during exercise. Scientists report in Integrative Biology that ...

Phosphorylated peptide detection

05-May-2009 - Itaru Hamachi and colleagues from Kyoto University have created a chemosensor that shows a high binding selectivity towards (i, i+1) bisphosphorylated peptide, displaying a dual-emission fluorescence change. 'Development of artificial chemosensors that can detect phosphorylated proteins or ...

Fluorescent fingerprints

23-Mar-2009 - Latent fingerprints at the scene of a crime can give vital clues in a criminal investigation. Giseop Kwak and colleagues from Kyungpook National University, in Korea, have successfully developed a technique to detect fingerprints in a convenient and non-destructive manner. Kwak and colleagues ...

Brushing up on sensors

14-Nov-2008 - Jason Locklin and his colleagues from the University of Georgia have developed covalently bound polymer brushes that can bind metal ions when irradiated with UV light. The polymer brushes, containing spiropyran moieties, were synthesised using atom transfer radical polymerisation ...

Blue fluorescent RNA: Tag your it!

04-Aug-2008 - An aptamer-dye pair has been developed as a fluorescent tag to monitor the RNA transcription process, by scientists in Japan. Shinsuke Sando, Yasuhiro Aoyama and colleagues from Kyoto University have chosen an RNA aptamer to selectively bind and 'light-up' a modified Hoechst dye. Usually the ...

Super-sensitive spray-on explosive detector

27-May-2008 - US scientists have designed a new spray-on explosive detector sensitive enough to detect just a billionth of a gram of explosive. After treatment the explosive glows blue under UV light, making it perfect for use in the field. William Trogler and his team at the University of California, San ...
