USA risk losing global leadership in nanotech

According to a new report from Lux Research, “In terms of sheer volume, The U.S. dominated the rest of the world in nanotech funding and new patents last year (…). But (…) countries such as China and Russia launched new challenges to U.S. dominance in 2009, while smaller players such as Japan, Germany and South Korea surpassed the United States in terms of commercializing nanotechnology and products.” (press release)

New clinical trial – capsaicin nanoparticles in patients with painful diabetic neuropathy

Mahidol University and the Thailand Research Fund recently started a phase II/III clinical trial involving a capsaicin nanoparticle preparation, now registered in the database under reference NCT01125215. According to this page, the aim is to “determine efficacy and safety of 0.75% topical capsaicin nanoparticle preparation versus placebo in patient with painful diabetic neuropathy“. The study is currently recruiting participants.

Nanoparticles risks vs benefits : the blogosphere trend

These charts were built by searching Google advanced blog search for posts respectively quoting nanoparticles (1st chart) ;  nanoparticles and risks / nanoparticles and benefits (2nd chart). The online mediatization of nanoparticles in the blogosphere appears to explode in 2005 and strongly increase from year to year ever since, with more visibility for the associated risks than benefits.

It is not very clear why 2005 would be the turning point, nevertheless it is interesting to confront these charts to a timeline of nanotechnology policy and regulation in Canada, Australia, the EU, the UK and the USA.

Gates Foundation funds innovative global health projects including sweat-triggered vaccine delivery using nanoparticles

The Bill & Melinda Gates Foundation announced a few days ago 78 grants of US$100,000 each for new innovative global health projects. Among those aiming at more effective vaccines, one involves nanoparticles : “Sweat-triggered vaccine delivery: Carlos Alberto Guzman of the Helmholtz Centre for Infection Research in Germany with Claus-Michael Lehr and Steffi Hansen of the Helmholtz-Institute for Pharmaceutical Research will develop nanoparticles that penetrate the skin through hair follicles and burst upon contact with human sweat to release vaccines.” (press release)
