TLDR Metallic-glass coated needles reduce skin trauma and improve tattoo quality.
The study investigated the effects of metallic-glass (MG) coatings on tattoo needles, finding that MG-coated needles significantly reduced skin trauma and improved tattoo quality. Experiments on pork samples and six live pigs showed that MG-coated needles reduced tissue adhesion and pigment spread, resulting in narrower, higher-density tattoo lines. Histopathological analysis revealed that wounds from MG-coated needles healed faster, closing within 2 hours, while those from bare needles remained open and inflamed for days. The MG coating reduced pigment spread by up to 57%, suggesting potential for high-resolution tattooing.
