One big challenge for gene therapies is delivering DNA or RNA safely to cells inside patients’ bodies. New nanoparticles could be an improvement over the current standard – repurposed viruses.
New ways to prepare and test nanoengineered particles are helping us understand how they can target diseases.

The more we learn about bio-nano science, the easier it will be to design nanoparticles that behave like we want them to.
The health scare surrounding nanoparticles might lead to people abandoning formula unnecessarily, with serious impacts on babies’ health.

A widely publicised study that cast doubt on the safety of milk formula was misleading, based on dubiously reported studies and may have serious consequences.
Coating paper with an inexpensive thin film can allow users to print and erase a physical page as many as 80 times. That reduces both the cost and the environmental effects of paper use.
Without electrons there would be no electron microscopes, and therefore no close-ups like this image of pollen.

The advent of electron microscopy and nanobiology has moved our appreciation of the living world to unprecedentedly small scales – with entirely new benefits and potential pitfalls to consider.
You’ll be amazed how much nanotechnology is found in the average house.

Two new studies from Food Standards Australia and New Zealand show there’s no evidence that nanoparticles in food present a health risk, but there’s more research to be done.
What’s in the bottle is good for me, right?

Microscopic needle-like particles don’t seem like something you’d want to feed a baby. Whether safe or not, the way we deal with nanoscale food additives leaves plenty of other questions.
We need to carefully assess nanomaterials to ensure their safety, but there are questions over whether the existing practice of risk assessment is up to the task.
It’s dirty work… and that’s only the visible dust.

Earlier this week, The Conversation reported that, “The future is bright, the future is … quantum dot televisions.” And judging by the buzz coming from this week’s annual Consumer Electronics Show (CES…
Recently the American publication Mother Jones published an article on the dangers of food laced with tiny metal oxide particles. The article, however, is laced with errors and misinformation. The source…
Nanoparticles — or nanomaterials, as they are often called — are chemical objects with dimensions in the range of 1-100 nanometres (nm). Particles this tiny are hard to imagine, but it may help to think…
