självläkningsförmåga

Självläkningsförmåga refers to the inherent capacity of living organisms and certain materials to repair damage and restore their original function. In biology, this concept is fundamental to understanding processes like wound healing, tissue regeneration, and the immune system's response to pathogens. Organisms have evolved complex mechanisms to detect injury, initiate repair processes, and clear away damaged cells or foreign substances. Examples range from the simple regrowth of skin after a cut to more remarkable feats like the regeneration of limbs in some amphibians or the repair of DNA damage within cells.

Beyond biology, the term "självläkningsförmåga" is increasingly applied in materials science and engineering. Self-healing materials are designed to autonomously repair damage, such as cracks or scratches, without external intervention. This can be achieved through various methods, including the incorporation of microcapsules containing healing agents that are released upon damage, or by designing materials with intrinsic properties that allow for bond reformation. The goal is to extend the lifespan and improve the reliability of structures and devices by enabling them to mend themselves when subjected to stress or wear. This area of research holds significant promise for applications in aerospace, automotive, construction, and electronics.
