|
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.
|
|
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.
|
|
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.
|
|
Medical technologists have fashioned synthetic nanoparticles to track down cancerous cells and to enable medics to differentiate cancerous cells from healthy cells. The technique should enable better targeted treatments.
|
|
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.

Studying the intestines of people is a critical part of the medical exam. The means to do this, using dyes, are not always the most efficient for a complete diagnostic. To improve this, researchers have looked at a pigment from spinach.
|
|
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.
|
|
Nanomedicine represents one of the most promising areas of medical technology. In a new application, researchers have used nanoparticles to address the effects of atherosclerosis.
|
|
Targeting drugs to the right spot within the human body is critical for the successful application of a medicine. Many compounds, however, don't hit the exact spot. New research is attempting to improve the focus of drug delivery.

With the world's population soon expected to reach eight billion, scientists have been working to find a way to produce enough food to feed all those hungry mouths. A team of engineers has found a way to do this using nanoparticles.
|
A biodegradable nanoparticle has been used to treat asthma and other allergies in a radically different type of research. The particles act in a way to stop the immune system from attacking an allergen and thus preventing the allergic response.
|
|
A new therapeutic drug for the treatment of prostate cancer has been trialed, and shown to be effective. The drug inhibits a protein known to contribute to the disease.
|
|
A means of combating aggressive breast cancer with a drug based on nanotechnology has been developed. In animal trials, metastatic cancer was successfully treated, paving the way for human trials.
|
|
Directing drug treatment to tumors is a hit-or-miss activity. Considerable research efforts are going into improving targeted drug delivery. A new approach centers on nanotechnology.
|
|
Austin -
Scientists have created a "bubble pen," and the technique of bubble-pen lithography, to inscribe nanoparticles onto a surface.
|
University of Michigan researchers have created a polymer sphere capable of delivering a molecule directly into bone wounds. The molecule instructs cells at the injury site to repair the damage.
|
|
A combination of nanoparticles, heat and ultrasound has proved effective for the elimination of tumors in studies conducted on mice.
|
|
Researchers in Japan have invented a new type of glue that is dry and non-sticky until it is crushed. Once broken up the substance acts like any other adhesive.
|
|
Food scientists are keen to find ways to boost food production, and one way to create novel foods is through the use of nanotechnology. One area under review is tomatoes.
|
|
Our food supply is not nearly as safe as we are led to believe, although it is much better than it was before we had the Food and Drug Administration. However, there are some disturbing gaps in food safety that the majority of us know little about.
|
|
Researchers have come up with a new nanoparticle that has the potential to become a targeted therapy for cardiac arrhythmia, a major cause of heart disease.
|
|
Swinburne University of Technology scientists have developed an even thinner form of graphene in preparation for next-generation devices, including nano-scale surgery.
