The instruments are believed to be safer than existing products made of stainless steel, cobalt-chromium alloy or nickel-titanium alloy, which cannot break down.
Shanghai Daily reports that the new products can break down into a small amount of hydrogen and magnesian or zinc ions gradually as patients recover. The hydrogen can be released outside the patient’s body and the magnesian or zinc ions can be absorbed by human beings healthily, the university’s scientists insist.
