일반 설명
Selenium is a non-metallic p-type semiconductor and is commercially produced as a by-product in refining sulfide-bearing copper minerals. It has good photovoltaic and photoconductive properties and is extensively used in the electronics such as solar cells, light meters, and, photocells. It also finds application in the field of ceramics, pigments, metallurgy, agriculture, glasses, and lubricants.
애플리케이션
Selenium has been used as a starting material tosynthesize selenium nanoparticles.

Selenium has been reported to have chemopreventive benefits in lung cancer. We conducted a double-blind, placebo-controlled trial to evaluate the incidence of second primary tumors (SPTs) in patients with resected non-small-cell lung cancer (NSCLC) receiving selenium supplementation. Patients with completely
