Zinc germanium phosphide is a semiconductor material that has been used as an effective cancer therapy. It is created by the reaction of zinc with germanium and phosphorus. This material has a high absorption coefficient in the infrared spectrum, which makes it useful for the treatment of skin cancers due to the cancer cells' increased absorption of infrared radiation. Zinc germanium phosphide can be grown at room temperature and has a constant refractive index over a range of wavelengths. The optical properties are determined by its lattice parameters, which can be changed to meet different needs. Techniques such as optical imaging and optical spectroscopy have been successfully employed to study this material's behavior.

Copper bromide is a chemical compound that contains copper and bromine. It is a salt that has been used to treat bowel disease, and has also been shown to have anti-inflammatory properties. Copper bromide can be synthesized by the reaction of copper chloride with sodium bromide in water. The electrochemical impedance spectroscopy showed that the redox potential of the copper atoms in this compound is 0.07 volts, which makes it an ideal candidate for use as a biological electrode. Copper bromide is soluble in water and reacts with nitrogen atoms, giving it detection sensitivity to nitric oxide. The thermal expansion coefficient of this compound is 5.5 × 10-6/°C, which means it will contract when heated or expand when cooled.
