Smart polymers: Chains that know when to make the clean cut
Keywords:
Smart polymers, controlled drug release, stimulus-responsiveAbstract
Smart polymers are materials that respond to stimuli, such as temperature or pH, and alter their structure to release drugs in a controlled manner. They function as “molecular guardians” that act only at the precise moment and location, enhancing effectiveness and reducing side effects. At the National Polytechnic Institute (IPN), these principles have been applied to develop an intelligent dressing for chronic wounds, which releases antimicrobial and healing compounds upon detecting an infection. Its low cost facilitates large-scale production and access in vulnerable communities. This approach holds promise for future applications in oncology, regenerative medicine, and infection control.
