- Bioengineers at ETH Zurich have developed a drug-free wireless electronic implant capable of removing excess glucose directly from the bloodstream to treat type 2 diabetes and obesity.
- The device uses a low-voltage catalyst made of gold, platinum, and graphite to convert blood sugar into gluconate, which is then excreted in urine by the kidneys.
- In mouse trials published in the journal Science, the implant normalised blood sugar levels within 90 minutes and reduced body weight by up to 10 per cent over six weeks.
- Controlled wirelessly via a continuous glucose monitor and smartphone, the system automatically activates when blood sugar spikes and shuts off once safe levels are restored.
- Although larger animal trials in pigs and sheep are planned next, independent experts cautioned that potential risks regarding human kidney function and electrolyte balance must be addressed first.
