<ul><li>Researchers at McGill University and Polytechnique Montréal have developed a new method for creating hydrogels using sound waves, making the process safer, faster, and more environmentally friendly.</li><li>Hydrogels, which are materials that can absorb large amounts of water, are traditionally made using chemical initiators. The new ultrasound method, called “sonogel,” forms hydrogels within minutes by creating tiny bubbles in a liquid precursor that collapse and solidify due to ultrasound waves.</li><li>The ultrasound method is faster, safer for the body, and kinder to the environment compared to traditional methods, completing the process in just five minutes and offering potential applications in medical use, tissue engineering, and 3D bioprinting.</li><li>This breakthrough technology, published in the journal Advanced Science, has the potential to revolutionize hydrogel production in medicine and industry, leading to less invasive medical treatments and more precise manufacturing techniques.</li></ul>
