A sunny outlook for Vitamin D detection

Abstract:
US researchers have developed a nanotechnology-based test to detect the important vitamin D metabolite calcitriol, the deficiency of which is an indicator of kidney failure.

Marc Porter and colleagues at the University of Utah in Salt Lake City have developed a test based on using surface enhanced Raman scattering (SERS) combined with gold nanoparticles. This new technique requires a much smaller sample volume and has no radioactive waste. 'Our work demonstrates that a simple optical method, when combined with gold nanoparticle labels, can outperform the standard methods heavily used in clinical diagnostic laboratories around the world,' says Porter.
