An Australian chemist has been toying with the potential to create fabrics from diamond nanothreads. The new material has considerable potential.

Crustaceans use nanotechnology to avoid predators

Many types of crustaceans found in the oceans are at the mercy of predators. To increase the chance of not being spotted many species have evolved camouflage, and the basis of this cloak of invisibility is nanotechnology.

Nanotechnology explains dust mite allergies

Dust allergies relates to mites that live and feed on dust particles (with most dust being composed of skin cells). Researchers have made a breakthrough in explaining allergies using nanotechnology.

Growing gold sharpened with a sewing machine

Growing gold like snowflakes and then sharpening it with a sewing machine-like device sounds like the stuff of fairy tales. In fact it is a scientific reality, based on cutting-edge research.

Bone healing advanced through crab shell protein

An advancement in nanotechnology: scientists have succeeded in combining a sugar, extracted from crab and shrimp shells, with nanomaterials. This is the building block for bone regeneration and wound healing.

Nanotechnology provides solution for oil spills

Oil spills are very difficult to address and cause significant ecological harm. A new method, based on nanotechnology, can turn an oil spill into a floating mass of brown jelly.

Stronger protection: New nanofiber renders material bullet proof

No clothing material is totally impregnable to a projectile but some are tougher than others, and researchers continue to make improvement. A new breakthrough at the nano-scale has been announced.

Nanoparticle injections protect joints from injury

A research study, using novel nanoparticles, where the particles are injected into joints, has protected cartilage from damage. This is based on studies in mice.

A step forward in safety: researchers have developed a fire resistant paper, based on nanowires. In addition, the paper is also bacterial resistant and this helps reduce the spread of infections.

Lab-on-a-chip technology promises early cancer detection

Researchers have developed new lab-on-a-chip technology that separates biological particles at the nanoscale. The technology could enable medics to detect cancer early and before symptoms appear.

Strengthening materials through nano-extracts from trees

Could parts of a tree be used to strengthen car bumpers and fenders? Could these biological parts be recycled from trees felled in the rainforest? This idea may seem bizarre but it has the potential to protect cars from bumps and crashes.

Bouncing nano-droplets remove contaminants

Imagine self-cleaning, hydrophobic surfaces and how useful they could be: windscreens that repel raindrops; airplane wings that de-ice, and so on. May sound like sci-fi, but it’s a step closer thanks to nanotechnology.

Portable device detects gluten in restaurants

People worried about gluten in food, especially in restaurants where the ingredients are uncertain, now have a helping hand thanks to a new device that can provide a quick and accurate assessment.

Nanobubbles turn heated water into power

Yale - Scientists have worked out how to generate energy from the low-temperature wasted heat produced by factories and power plants. This promises a new wave of low cost energy.
