Introduction

Metallic materials have a long and varied history in the life sciences. For centuries, the metals themselves have been used in medical and biological applications, from artificial implants to surgical aids. More recently, the use of metallic materials in the life sciences has extended beyond simple tools and into the fields of analytical instrumentation as well as integrated products such as diagnostic devices, drug delivery systems, and artificial organs. This has been driven by the need for materials that can perform a wide range of complex and intricate functions in a manner that is both reliable and cost-effective. As such, the research into, and development of, metallic materials in life sciences has become increasingly important to the advancement of science and medicine.

Biomedical Implications of Metallic Materials

Bio-metallic materials provide unique advantages to the biomedical industry and can offer solutions to a range of needs. Perhaps the most noticeable benefit of the use of these materials is their relative strength and durability. These qualities make them ideal for use in prosthetic devices and for components of micro-instruments — such as those designed for biomedical imaging — that must withstand the mechanically demanding environment of the human body. Metals can also be formed into intricate, miniature components and surfaces which enable the fabrication of functional devices that can serve as alternatives to, or replicas of, human organs and tissues. Finally, metal materials can be engineered with a range of attributes such as corrosion resistance, thermal conductivity, electrical conductivity, and optical properties, for use in a wide range of biomedical instrumentation and applications.

Recent Advances in Biomedical Metallic Materials

Recent advances in biomedical metallic materials have enabled the development of a range of innovative products and solutions. One such example is the implementation of nanomaterials such as silver, gold, and magnesium alloys, which can be made into ultra-thin layers and used as tissue scaffolds for tissue engineering. These materials can be engineered to possess properties that are beneficial to the growth of cells and tissue by, for example, providing a surface to which cells can attach and grow, or even releasing biologically beneficial compounds such as antibiotics. This type of material is also beneficial for imaging devices, as the incorporation of metals can improve their visualization capability through the formation of nanostructures.

Another example of recent progress in biomedical metallic materials is the development of metallic sensors. These devices are capable of detecting very small levels of bio-chemicals or compounds in solutions or the environment, making them ideal for diagnostic and therapeutic devices such as glucose monitors. In addition, metallic sensors can be utilized in drug delivery systems, where they can serve as triggers for the release of drugs upon detection of a target compound or physiological change in the patient’s body.

Conclusion

Metallic materials have long been used in the life sciences, but recent advances have enabled the development of an even wider range of applications for these materials. Bio-metallic materials can be tailored to possess a variety of desirable properties, such as strength and durability, corrosion resistance, and the ability to facilitate biological processes, making them ideal for medical and biological instruments, implants, and drug delivery systems. Metallic sensors have also been developed to detect tiny concentrations of substances for use in a variety of diagnostic and therapeutic solutions. As research in this field continues to advance, the opportunities for such materials in life sciences will continue to expand.

Biomaterials composed of metals have a long history of use in the medical field. Going as far back as ancient times, gold rings were used to close cranial wounds and the ancient Egyptians used gold wires to replace damaged arteries. Even now, the use of metal biomaterials remains widespread.

Metallic biomaterials can be broadly grouped into two categories: barrier materials and implant materials. As their name suggests, barrier materials are used to provide a physical barrier between areas of the body. Examples include wires, pins and screws, and stents in cardiovascular applications. Implant materials, on the other hand, are more complex and functional in nature. Commonly used for bone and joint repair, and for artificial implants, such materials may be used to mimic the innate physical properties of the body and to provide anti-corrosive and wear-resistant properties.

The most commonly used metallic biomaterials include stainless steel, titanium and cobalt-chromium alloys. Stainless steel has excellent mechanical properties, great corrosion resistance and excellent biocompatibility; it is also inexpensive, making it ideal for surgical instruments and devices. Titanium is also highly corrosion resistant and has great biocompatibility. It is commonly used in applications such as knee replacements, bone plates and screws, and dental implants. Cobalt-chromium alloys combine great strength and biocompatibility, making them excellent materials for hip, knee and shoulder implants.

In recent times, new advances in biometals have enabled the production of advanced materials with tailored properties. For example, bimetallic composites employing two layers of different metals, joined by a diffusion bonding layer, can be used to provide greater strength and wear resistance. Additionally, porous metals can be produced that increase the surface area for improvedbone fusion.

Overall, metallic materials are playing an increasingly important role in medical applications. Not only are they strong, corrosion-resistant and biocompatible, but they are also easy to manufacture, making them an attractive option for use in from surgical instruments to complex implants.
