Current application of nonferrous metal-based materials in biomedicine

The use of biomedical materials has a long history, dating back to 3500 BC when the ancient Egyptians used cotton fibers to close wounds. There are various types of biomedical materials, and nonferrous metal-based materials are one of important choices. In recent years, nonferrous metal-based materials have been widely used in the biomedical field due to their excellent biocompatibility, favorable mechanical properties and atractive photothermal conversion abilities, demonstrating great potential in promoting patient care. This review summarizes the research achievements of nonferrous metal-based materials in the fields of interventional consumables, cancer treatment, precise diagnosis and biosensor, which includes the application forms of some elements like titanium, magnesium, tantalum, gold, bismuth, copper, platinum, etc. and their alloys, and displays their characteristics in clinical practice and current research focus. In the end, several possible directions are prospected for the future development of nonferrous metal-based materials in biomedical engineering.
