The Experimental Biology 2003 symposium entitled "New Technologies for Nutrition Research" was organized to highlight new and emerging technologies, including nanotechnology and proteomics, and to suggest ways for their integration into nutrition research. Speakers focused on topics that included accelerator mass spectrometry for ultra-low level radiolabel tracing, nanodevices for real-time optical intracellular sensing, mass spectrometric techniques for examining protein expression, as well as potential applications for nanotechnology in the food sciences. These technologies may be particularly useful in obtaining accurate spatial information and low-level detection of essential and nonessential bioactive food components (nutrients) and their metabolites, and in enhancing the understanding of the impact of nutrient/metabolite and biomolecular interactions. Highlights from this symposium are presented briefly herein.

KEY WORDS: • bioactive food components • food science • accelerator mass spectrometry • nanotechnology • proteomics
