Exploding Gas Bubbles Could Kill Cancer Cells
Tiny bubbles, the size of less than one tenth of the width of a human hair, could be the next weapon in fighting cancer cells.
Leeds University engineers and cancer specialists are developing a new exploding bubbles technique that can punch small holes in cancer cells, allowing drugs to get inside cancerous cells while reducing the attacks on healthy cells nearby. These microbubbles are already used to provide clearer ultrasound scan images because the gas in the bubble better reflects the ultrasound pulse when injected through the blood stream.
“By targeting the bubbles to the cancerous tissue, it means we can deliver far higher concentrations of drug to the tumour than is normally possible in chemotherapy.”
