MBE and Proteins

Two new works out this week. Both key works for our lab. In the first we show that the deposition of charged particle beams can in fact be equivalent to conventional molecular beam epitaxy.

Crystalline Inverted Membrane Growth by Electrospray Ion Beam Deposition in Vacuum.

inverted membrane deposition

 

The second one is even nicer: We deposited proteins a while a ago and found so many things you can do with them in vacuum: deposit them folded and unfolded and refold them and in the end look at the single amino acid. Now we only need to find a way to know which amino acid you see.
