Melanins produced synthetically and isolated from biological systems act as an amorphous semiconductor threshold switch. Switching occurs reversibly at potential gradients two to three orders of magnitude lower than reported for inorganic thin films, and comparable to gradients existing in some biological systems. Of a number of other biological materials tested, only cytochrome c acted similarly, but at the high potential gradients reported for thin film amorphous semiconductors.
合成制备并从生物系统中分离出的黑色素可作为一种非晶态半导体阈值开关。开关在比无机薄膜所报道的低两到三个数量级的电位梯度下可逆发生，且与某些生物系统中存在的梯度相当。在测试的许多其他生物材料中，只有细胞色素c表现出类似特性，但却是在薄膜非晶态半导体所报道的高电位梯度下。
