It occurs to me that the techniques described in this article could have a wide variety of applications outside the biological sciences. For example, imprinted high-temperature ceramic materials could be used as less-expensive catalysts in automobiles and factory emission-controls systems. And filters made from such materials might be used to greatly reduce the quantity of […]
