Faking the Golgi

Researchers led by Rensselaer Polytechnic Institute's Robert Linhardt developed a prototype of an artificial Golgi complex based on a digital microfluidic chip. The researchers then used the chip to modify heparan sulfate chains. "This represents the first enzymatic modification of an immobilized substrate in a digital microfluidic device and a critical first step in the creation of an artificial Golgi," the researchers write.
