Two-Tone Molecular Printing

Nanopipette with two chambers produces microstructures made of biomolecules.

The emblem of the Cambridge University, a portrait of scientist Isaac Newton, rendered in microscale as a colorful, fluorescing image: are British researchers just playing around? No, it’s a "finger exercise" for serious science. For modern, miniaturized analytical and diagnostic processes, it is necessary to attach microstructures made of different biomolecules to tiny supports with high precision.
