February 25, 2015 – Researchers from Singapore’s Institute of Bioengineering and Nanotechnology (IBN) of A*STAR and Quebec’s IREQ (Hydro-Québec’s research institute) have synthesized silicate-based nanoboxes that could more than double the energy capacity of lithium-ion batteries as compared to conventional phosphate-based cathodes. This breakthrough could hold the key to longer-lasting rechargeable batteries for electric vehicles and mobile devices.

“IBN researchers have successfully achieved simultaneous control of the phase purity and nanostructure of Li2MnSiO4 for the first time,” said Professor Jackie Y. Ying, IBN Executive Director. “This novel synthetic approach would allow us to move closer to attaining the ultrahigh theoretical capacity of silicate-based cathodes for battery applications.”

IBN’s Wound Healing Nanogels Named 10 Asian Biotech Innovations to Watch in 2015

The wound healing nanogels developed by Dr Charlotte Hauser and her group at IBN has been named one of “10 Asian Biotech Innovations to Watch in 2015” by Asian Scientist magazine in its January – March 2015 issue. The scientists have developed hydrogels composed of nanofibrous networks of short and easily synthesized peptides that self-assemble to nanofibers when water is added. The nanogels were shown to heal burns more quickly compared to conventional wound dressings. Accelerated wound healing is crucial to minimizing the risk of infection and scarring, both of which are common problems faced by burn patients. These gels can be used as a topical gel, spray, membrane patch or long-lasting dry-powder formulation. See article in Asian Scientist.

Giving Infections the Brush Off
Metal-free catalysis generates brush-like polymer coatings that prevent build-up of toxic fouling films on medical devices

February 4, 2015 – A ‘one-step’ coating that blocks protein growth and kills surface-bound bacteria on silicone may significantly reduce infections from medical devices such as catheters, finds a study led by researchers from the Institute of Bioengineering and Nanotechnology (IBN). Dr Yi Yan Yang and international co-workers accomplished this with a synthetic technique that combines biomimetic surface adhesion and antimicrobial capabilities into a brush-like polymer film.

Implanting foreign materials into biological environments inevitably leads to accumulation, or ‘fouling’, of surfaces with pathogenic biomolecules. To block this film growth, researchers from IBN are experimenting with coatings known as ‘polymer brushes’ – arrays of macromolecular chains that bind to surfaces and modify properties such as bioadhesion.
