Polycarbonates to Tackle Multidrug Resistance
Polymers that can be fine-tuned for optimal effect could help fight multidrug-resistant infections

July 2, 2014 – The rise of drug-resistant microbes is a major challenge facing medicine. The World Health Organization’s 2014 report on global surveillance of antimicrobial resistance warns of the very real possibility of the twenty-first century becoming “a post-antibiotic era – in which common infections and minor injuries can kill”. In the face of this threat, researchers worldwide are exploring approaches to find new compounds that combine selective antimicrobial efficacy with low toxicity toward mammalian cells.
Dr Yi Yan Yang at the Institute of Bioengineering and Nanotechnology and co-workers have now created a range of large polycarbonate molecules that are potent antimicrobials and are tolerated well by rat red blood cells, suggesting that they could prove similarly effective in humans. Crucially, by subtly varying the composition of the polycarbonate molecules, the researchers could fine-tune the selectivity and activity of these candidate drugs.
A ‘Click’ Toward Localized Chemotherapy
‘Click’ chemistry produces a hydrogel with less toxicity and greater tissue localization in a mouse cancer model

June 4, 2014 – Platinum-based chemotherapy drugs are commonly used to treat a wide variety of solid tumors, including cancers affecting the breast, colon and lung. However, only a small amount of these anticancer drugs typically reaches the target organ system. This inefficiency not only reduces the efficacy of the drug; it also leads to severe side effects, ranging from nausea to kidney toxicity or deafness.
Dr Charlotte Hauser and her co-workers at the Institute of Bioengineering and Nanotechnology have now developed a platform for the localized and sustained release of platinum-based anticancer therapeutics that overcomes many of these limitations. The research team’s novel gel formulation - a combination of specialized peptides and the drug oxaliplatin - led to dramatic growth inhibition when injected directly into the breast tumors of mice. In addition, the gel treatment produced a better tolerance profile than standard oxaliplatin drug therapy.
Using Gold Nanoprobes to Unlock Your Genetic Profile
For more accurate prescription for stroke and heart patients

May 29, 2014 – A fast and cost-effective genetic test to determine the correct dosage of blood thinning drugs for the treatment of stroke, heart problems and deep vein thrombosis has been developed by researchers at the Institute of Bioengineering and Nanotechnology (IBN). Using gold nanoprobes, this new technology offers personalized healthcare based on the genetic profile of the patients.
IBN Executive Director Professor Jackie Y. Ying said, “Diseases caused by blood clots can be potentially fatal. Genetic testing can improve the treatment of such medical conditions. By combining our expertise in molecular diagnostics and nanotechnology, we have developed a new genetic test that can determine the appropriate drug dosage to be administered for each patient.”
Blood thinning drugs or anticoagulant medication prevent clots from forming in the blood. They are used to treat stroke, irregular heartbeat and deep vein thrombosis.
