Polymer armour beefs up enzymes
Biological enzymes could have a number of applications outside the cell, but the molecules tend to unfold, or denature, when they are outside their natural environment. Now, researchers at the Pacific Northwest National Laboratory, US, have used a polymer coating to protect enzymes. The resulting single-enzyme nanoparticles remained active for five months rather than just a few hours.
