New opportunities from old chemistry in surface science Some century-old chemistry could have a strong impact on important issues in biosensors and other nanotech devices, according to a Purdue University research group.A team led by Alexander Wei has shown that amines, a large and important class of organic molecules, when mixed with carbon disulfide, can bond to gold more robustly than thiols, which are commonly used materials for giving new functions to metal surfaces.
