Describe two other “medicinal” uses for metals.

Please see "Explanation" for a description of how and why these two metals work in the medical field.

1. Platinum (Pt) is used in chemotherapy.

2. Nickel (Ni) used in medical tools and equipment.

Explanation:

Two chemotherapy agents contain the heavy metal Platinum. Those agents cause crosslinking in DNA, making it impossible for the dividing cancer cell to duplicate it's DNA, eventually leading to the death of that cancer cell. Platinum allows the DNA's bases to magnetically crosslink, and without platinum, there wouldn't be enough magnetic energy to cause this.

Nickel-containing stainless steel is also widely used in manufacturing medical devices, pharmaceuticals and vaccines, where the highest standards of hygiene and sterility are essential.
