Robotics in the lab -SPRi and Mass Spectrometry

In the team of Dynamics of Macromolecular Complexes at the LBPA  we developed a technique to transfer material from an SPRi prism to a SELDI (mass spec) slide. This technique had already been published by us some years ago (see Bouffartigues 2007):

Using the Hamilton Starlet robot we were able to automate this such that a given spot on the surface could be treated with a chaotropic solution then transferred to a SELDI surface for identification by mass spectroscopy. We used a pin tool and modified the programming to reduce contact between the pin tool and the rather fragile (50nm thick) gold surface of the prism.

Next time we will get David Arraez to shoot it for us 🙂
