Nanoparticles for non-invasive photodynamic therapy of deep cancer

National University of Singapore researchers at the Faculty of Engineering's Department of Bioengineering have discovered a new technology that paves the way for a new safe and non-invasive method of treating deep cancer. Led by Associate Professor Zhang Yong, the team has so far, proven that their technology could inhibit tumour growth and control gene expression in mice. This is a world's first for the use of nanoparticles for non-invasive photodynamic therapy of deep cancer.

‘C’ variant disrupts brain connectivity in children with ASD

Over the past decade, researchers have made great strides in identifying genes that lead to an increased risk of autism spectrum disorders (ASD), which result in a continuum of social deficits, communication difficulties and cognitive delays. But it's still critical to determine how exactly these genetic risk factors impact the brain's structure and function so that better treatments and interventions can be developed.
