Indigestible nanotech claim

In a widely circulated report by the Chicago Tribune's Jon Van, Lack of nanotech safety research 'serious', Andrew Maynard, a science adviser to the Woodrow Wilson Center's project on emerging nanotechnologies, is quoted as saying:

"No projects are specifically addressing the potential effects of nanomaterials in the gastrointestinal tract. Given the large number of current nanoproducts that are supposed to be eaten, such as food and nutritional supplements, that is a curious and serious omission."

A simple search reveals this claim to be false. Here are only a few I had time to find:

  • Gastrointestinal persorption and tissue distribution of differently sized colloidal gold nanoparticles
  • Nanoparticle uptake by the rat gastrointestinal mucosa: quantitation and particle size dependency
  • Preliminary Results on the Effects of Oral Administration of Two Types of Nanoparticles in the Rat
  • Oral uptake and translocation of a polylysine dendrimer with a lipid surface
  • Enhanced oral uptake of tomato lectin-conjugated nanoparticles in the rat
  • Factors affecting the oral uptake and translocation of polystyrene nanoparticles: histological and analytical evidence
  • Mucoadhesion of polystyrene nanoparticles having surface hydrophilic polymeric chains in the gastrointestinal tract

    Nicely done ... I suspect that Mr. Maynard is merely trying to bolster his own claim for government grant money.
