Penning a protein pattern

Patterns of proteins with nanoscale features can be written directly onto a surface using a 'nanofountain pen', a very narrow pipette attached to a scanning probe microscope. This technique should enable the preparation of 'protein chips' with a very high density of features that will function in an analogous manner to gene chips, allowing snapshots to be taken of a cell's active proteome.
