Infected wounds pose a significant medical challenge, often leading to delayed healing and complications due to bacterial biofilms and excessive inflammation. A key characteristic of these infection sites is an acidic microenvironment. Scientists have now engineered a smart nanoplatform that uses this acidity as a trigger to release a potent combination of therapeutic agents directly at the wound site.

In an article appearing in the journal Biomedical Analysis, researchers from Sun Yat-sen University describe the development of a novel nanocomposite, SH@ZIF-8/AgNPs. This platform consists of a porous carrier called a zeolitic imidazolate framework-8 (ZIF-8), which is loaded with shikonin (SH), a natural compound with anti-inflammatory and antioxidant properties. The surface of this carrier is then decorated with silver nanoparticles (AgNPs), which are well-known for their broad-spectrum antibacterial activity. The design enables the encapsulation of a high concentration of shikonin within a stable structure.

The Ceramics Industries Research Association (AICE), in collaboration with the Universitat Jaume I of Castelló and 15 additional partners, is developing a project to test safe and clean industrial technologies that reduce risks to human health and biodiversity. The project is linked to the new Environmental Engineering Laboratory, whose technical committee includes Irina Celades and Eliseo Monfort. The project kick-off meeting was held on 15 and 16 June at the headquarters of the Ceramic Technology Institute (ITC) on the UJI campus. BRISA addresses the urgent challenge posed by emerging airborne industrial pollutants, which are linked to approximately 125,000 deaths annually. The aim is that its implementation in 600–800 industrial facilities will protect more than 45,000 workers by 2035, prevent hundreds of premature deaths each year, and reduce material consumption by 5% and energy consumption by 15%.
