The Bitter Pill: Smoke, Mirrors and Nanotechnology
Alternative health practitioners are quick to offer a variety of untested therapies. Nanotechnology is yet another in the list.
Expert Opinion: Nanotech Cleared in Food Additives and Packaging
Food Standards Australia New Zealand has released two reports reviewing the evidence for the safety of nanotechnologies in food packaging and in food additives. Based on patent searches rather than on nanotech declarations to the regulator, the reports suggest there is no direct evidence that novel nanomaterials are currently being used in food packaging applications in Australia or New Zealand.
Up Close: Toxic titbits? The effects of nanoparticles on our health
Bio-nanoscience investigator Prof Kenneth Dawson discusses current research into nanoparticles and their potential effects on our health.
Up Close: Useful imperfections: Nanodiamonds for quantum sensors in living cells
Physicist Prof Lloyd Hollenberg explains how quantum technologies are leading to the development of sensors of only a few atoms’ size – small enough to be placed inside living cells to enable monitoring of biological processes.
