Nanomedicine could scupper the need for TB patients to take multiple daily tablets with toxic side effects.
The reason that nanoparticles hold such hope for TB treatment is that they can be carefully targeted.

Gold can be used to make jewelry, but also to fight cancer. Several clinical trials are currently underway in the United States where patients are being treated with gold nanoparticles.
Subbing new risks for the current dyes’ dangers?
Less-toxic hair dye would be a great invention. But discounting the risks that come with nanoparticles could undermine other efforts to protect human health and environmental from their effects.
Delivering genetic material is a key challenge in gene therapy.

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.
Achievement unlocked: Rewritable paper.
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.
From the kitchen sink to the laundry and garage -- nanotechnology has already made its way into the average household.
Tastier salt, packaging that alerts you to food that has gone off and fish oil that tastes better – nanoparticles have lots of potential.
Some companies have used nano-titanium dioxide to make powdered sugar on donuts whiter.
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.
A single-atom engine is the latest example of how nano-technology can create machines to power tiny robots inside the body.
With reserves of indium tin oxide running low, what will replace it as the leader in transparent conducting materials?
Touch screens are everywhere these days but the materials commonly used to make them are not that abundant. So what are the alternatives?
A new method for creating a form of graphene with carbon dioxide sucked from the air has been announced with misleading claims.
Substances, such as these carbon nanotubes, can behave differently at the nano-scale, and may post a health risk.
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.
Tiny nanoparticles emitted during building work can enter your lungs and bloodstream.
Nanoparticles: small but deadly… to cancer.
New research could into nanoparticles could help deliver drugs straight to the site of tumours and make them more effective when they get there.
The picture is awesome… but am I risking my health?
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…
Drink without worry.
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…
