How Heavy Metals Are Escorted into Cells (video) Worcester Polytechnic Institute Share Print E-Mail Loading video... Caption José Argüello, Walter and Miriam Rutman Professor of Chemistry and Biochemistry at Worcester Polytechnic Institute (WPI), studies the biochemical ballet by which cells transport metal micronutrients, such as copper, zinc, cobalt, and iron, across their membranes and to the sites where they play such fundamental roles as helping blood transport oxygen or plants fix nitrogen from the air. It is fundamental research with important implication for real-world concerns, including the treatment of diseases like tuberculosis.
