These findings are a step forward in the development of targeted therapies for hard-to-treat cancers. Oleh Taratula, Ph.D., an assistant professor in the Oregon ...

Picturing peanut contamination with near infrared hyperspectral imaging

07-Apr-2015 - Study the label of almost any food product and you’re likely to see the rather vague warning “May contain peanuts” somewhere on there, unless of course it’s a product that definitely does contain peanuts. As now revealed in a paper in JNIRS - Journal of Near Infrared Spectroscopy, these warnings ...

3D IR images now in full color

Berkeley Lab and University of Wisconsin researchers unveil FTIR spectro-microtomography

07-Aug-2013 - An iconic moment in the history of Hollywood movie magic was born in the 1939 film The Wizard of Oz when Judy Garland as Dorothy Gale stepped out of the black and white world of Kansas into the rainbow colored world of Oz. An iconic moment in the history of infrared imaging may have been born ...

High throughput phenotyping of uropathogenic E. coli isolates with Fourier transform infrared spectroscopy

01-Feb-2013 - UK scientists have designed a high throughput method to determine the phenotypes of the different Escherichia coli strains that cause urinary tract infections. The method couples bacterial growth requirements to Fourier transform infrared spectroscopy. The majority of urinary tract infections are ...
