DNA-testing smartphone aims to tackle drugs resistance
Scientists have built a DNA-analysing smartphone attachment that is a fraction of the cost of lab-based kit.
The creators of the phone-powered pathology microscope believe, it could be mass produced for less than $500 (£406) a unit.
They say it could help doctors treat cancer, tuberculosis and other diseases more effectively than is sometimes possible in the developing world.
But a UK firm says it is developing a more advanced and cheaper alternative. Details of the peer-reviewed project are published in the journal Nature Communications.
