Gold nanoparticles are made up of metallic gold atoms to create a crystal structure of 1-100 nm.

Gold nanofibers in engineered heart tissue can enhance electrical signalling, find researchers

Heart tissue sustains irreparable damage in the wake of a heart attack. Because cells in the heart cannot multiply and the cardiac muscle contains few stem cells, the tissue is unable to repair itself - it becomes fibrotic and cannot contract properly.

Bioapplications of nanoparticles: an interview with Dr Catherine Berry, University of Glasgow

These particles are all classed as inorganic particles, which can all be utilised in biomedical applications. They differ in terms of their inherent material and size dependent physiochemical properties, for example, their optical and magnetic properties.

Researchers make gold nanoparticles more effective against ovarian cancer cells

Positively charged gold nanoparticles are usually toxic to cells, but cancer cells somehow manage to avoid nanoparticle toxicity. Mayo Clinic researchers found out why and determined how to make the nanoparticles effective against ovarian cancer cells.

Protein tumor necrosis factor-alpha is a powerful weapon to control cancer

The protein tumor necrosis factor-alpha (TNF-alpha) is a powerful weapon in the arsenal to control cancer. Unfortunately, as is the case with many potent cancer therapies, the use of TNF-alpha as an anti-cancer therapy has been severely limited.

Scientists develop new technique for imaging nanoparticle dynamics with atomic resolution

The macroscopic effects of certain nanoparticles on human health have long been clear to the naked eye. What scientists have lacked is the ability to see the detailed movements of individual particles that give rise to those effects.

DNAzymes, gold nanoparticles and disease detection: an interview with Dr Chan and Kyryl Zagorovsky, University of Toronto

Gold nanoparticles are tiny spherical particles made out of gold atoms with sizes on nanometre scale. This is around 1,000 times smaller than the thickness of human hair.

Expert to explain how extremely stable gold nanoparticles can be used in medicine

A nanoscale science expert will explain how extremely stable gold nanoparticles can be used in medicine. Professor Mathias Brust, of the University of Liverpool, will give his lecture Monolayer Protected Clusters of Gold: Building Blocks, Functional Materials, Macromolecules, Biomedical Tools and more at the University of Leicester on Thursday, February 21.

DNAzymes and gold nanoparticles used to detect infectious diseases

Infectious diseases such as malaria and syphilis can be diagnosed rapidly and reliably in the field by using a simple test developed by Canadian scientists. The test is based on the use of DNAzymes and gold nanoparticles. As the researchers report in the journal Angewandte Chemie, their test allows for the sensitive detection of bacteria, viruses, and parasites.

New gold nanoparticle can transport powerful radioactive particles directly to tumors

We've all heard that "it's not wise to use a cannon to kill a mosquito." But what if you could focus the cannon's power to concentrate power into a tiny space? In a new study, University of Missouri researchers have demonstrated the ability to harness powerful radioactive particles and direct them toward small cancer tumors while doing negligible damage to healthy organs and tissues.

Researchers turn light into heat on the nanoscale to trigger biochemical reactions

Since Edison's first bulb, heat has been a mostly undesirable byproduct of light. Now researchers at Rice University are turning light into heat at the point of need, on the nanoscale, to trigger biochemical reactions remotely on demand.

Tufts University researchers demonstrate silk-based implantable optics

Tufts University School of Engineering researchers have demonstrated silk-based implantable optics that offer significant improvement in tissue imaging while simultaneously enabling photo thermal therapy, administering drugs and monitoring drug delivery. The devices also lend themselves to a variety of other biomedical functions.

BRIGHTs bind to biomarkers of disease and light up to reveal their location

Called BRIGHTs, the tiny probes described in the online issue of Advanced Materials on Nov. 15, bind to biomarkers of disease and, when swept by an infrared laser, light up to reveal their location.

Radioactive gold nanoparticle treatment safe and effective in dogs with prostate cancer

Currently, large doses of chemotherapy are required when treating certain forms of cancer, resulting in toxic side effects. The chemicals enter the body and work to destroy or shrink the tumor, but also harm vital organs and drastically affect bodily functions. Now, scientists at the University of Missouri have proven that a new form of prostate cancer treatment that uses radioactive gold nanoparticles, and was developed at MU, is safe to use in dogs.

UMass Amherst develops 'chemical nose' array to detect metastatic cancers

In the fight against cancer, knowing the enemy's exact identity is crucial for diagnosis and treatment, especially in metastatic cancers, those that spread between organs and tissues. Now chemists led by Vincent Rotello at the University of Massachusetts Amherst have developed a rapid, sensitive way to detect microscopic levels of many different metastatic cell types in living tissue. Findings appear in the current issue of the journal ACS Nano.
