As we celebrate the MOF Nobel I want to highlight Omar Yaghi's words 8th Oct.: “Smart people, talented people, skilled people exist everywhere. That’s why we really should focus on unleashing their potential through providing them with opportunity.” And he takes action! news.uj.ac.za/news/nobel-l...

Mechano‐Bactericidal Surfaces Achieved by Epitaxial Growth of Metal–Organic Frameworks

Mechano‐Bactericidal Surfaces Achieved by Epitaxial Growth of Metal–Organic Frameworks

Mechano-bactericidal surfaces based on metal–organic frameworks (MOFs) are designed using a MOF-on-MOF strategy. Two methods of MOF surface assembly, in situ growth and ex situ dropcasting, are applied. Distinct mechano-bactericidal actions are discussed, including stretching, impaling, and mechanical injury. Abstract Mechano-bactericidal (MB) surfaces have been proposed as an emerging strategy for preventing biofilm formation. Unlike antibiotics and metal ions that chemically interfere with cellular processes, MB nanostructures cause physical damage to the bacteria. The antibacterial performance of artificial MB surfaces relies on rational control of surface features, which is difficult to achieve for large surfaces in real-life applications. Herein, a facile and scalable method is reported for fabricating MB surfaces based on metal–organic frameworks (MOFs) using epitaxial MOF-on-MOF hybrids as building blocks with nanopillars of less than 5 nm tip diameter, 200 nm base diameter, and 300 nm length. Two methods of MOF surface assembly, in situ growth and ex situ dropcasting, result in surfaces with nanopillars in different orientations, both presenting MB actions (bactericidal efficiency of 83% for E. coli ). Distinct MB mechanisms, including stretching, impaling, and mechanical injury, are discussed with the observed bacterial morphology on the obtained MOF surfaces.

Internationella kemiunionen IUPAC arbeta också med jämlikhetsfrågor. Alla behövs i arbetet med att fixa de stora problem som mänskligheten står inför och där kemi är en viktigt bit av lösningen. Vi har inte råd att förlora några talanger.
