Sydney, 12.05.2022 (SciDev.Net): A nanotech imaging device, tiny enough to fit on a smartphone camera lens, has the potential to make the diagnosis of certain diseases accessible and affordable for people in rural and remote regions, say Australian scientists who developed it.

The COVID-19 pandemic has brought diagnostics into sharp focus and the World Health Organization has called on countries to prioritise investments in quality diagnostics as the first step in control, treatment and prevention of disease.

The scientists from the University of Melbourne and the Australian Research Council Centre of Excellence for Transformative Meta-Optical Systems (TMOS) published details of the device in the journal ACS Photonics.

Sydney, 14.04.2008 (IPS): While millions of children’s lives have been saved as a result of a successful worldwide campaign to boost vaccination programmes, governments across the world are failing in following through on their commitments to health aid and the Millennium Development Goals (MDGs).

‘’Wealthy countries such as the G8 members continue to content themselves with largely symbolic gestures. We have to make sure that the pledge made by governments (on MDGs) is followed,” eminent medical scientist Gustav Nossal told IPS.
