A new plastic surgery material with high safety and antibacterial properties was synthesized from blue mussel shells by scientific researchers and international cooperation team of Russian national research and Technology University (NUST misis). The related research results were published in the international ceramic journal.
Yevgeni Kolesnikov, a researcher at nust misis functional nanosystems and high temperature materials, said that implant infection is still a major problem in plastic surgery, which can be solved theoretically by creating antibacterial biomaterials. As we all know, hydroxyapatite is the main component of bone and teeth, and is the best material to produce new bone tissue and replace damaged bone. It has biocompatibility and bioactivity, and can be easily integrated into bone tissue and adjacent tissue. Hydroxyapatite can interact with osteoblasts and actively induce their growth and division.
At present, hydroxyapatite is widely used in maxillofacial surgery, dentistry and plastic surgery as filler and cover. Researchers in many countries use eggshell, coral, fish bone and other raw materials to produce hydroxyapatite. However, due to the complex synthesis process, mass production of hydroxyapatite is still challenging. Using blue mussel shells as raw materials, Russian and Indian research teams have developed rapid production of hydroxyapatite nanoparticles containing magnesium particles by microwave synthesis (in which polyvinylpyrrolidone is also used).
Yevgeni Kolesnikov said the hydroxyapatite nanoparticles synthesized by their team contain magnesium particles because of their biocompatibility and antibacterial properties. The average content of magnesium in adults is 24 grams. Lack of this trace element can lead to diabetes, cardiovascular disease, hypertension and osteoporosis.
Yevgeni Kolesnikov said that the researchers tested the toxicity of hydroxyapatite nanomaterials containing magnesium particles in zebrafish embryos, and confirmed that the material was non-toxic and safe, and could be used in the medical field to produce plastic surgery materials.
