Singapore researchers make 'fat-burning' skin patch for â¹240
Researchers at Nanyang Technological University, Singapore have developed a skin patch that uses micro-needles to deliver drugs which turn energy-storing white fat into energy-burning brown fat. The prototype, at a material cost of S$5 (about â¹240), curbed weight gain in mice on a high-fat diet and reduced their fat mass by more than 30% over four weeks, said the researchers.
