Insulin cream offers needle-free option for diabetes

<h2>00:45 A molecule that delivers insulin through the skin</h2><p>Researchers have developed a skin-permeable polymer that can deliver insulin into the body, which they say could one day offer an alternative to injections for diabetes management. The skin’s structure presents a formidable barrier to the delivery of large drugs but in this work a team show that their polymer can penetrate though the different layers without causing damage. Insulin attached to this polymer was able to reduce blood glucose levels in animal models for diabetes at a comparable speed to injected insulin. While further research is required on the long-term safety of this strategy, the team hope it could offer a way to non-invasively deliver other large-molecule drugs into the body.</p><br><p><em>Research Article:&nbsp;</em><a href="https://www.nature.com/articles/s41586-025-09729-x" rel="noopener noreferrer" target="_blank"><em>Wei et al.</em></a></p><p><br></p><h2>09:23 Research Highlights</h2><p>How extrem...
