Matter-wave interferometry with biological nanomatter [1,2] explores the frontier between quantum physics, biochemistry, nanotechnology, asking how biological structure affects quantum-delocalization and if biology can provide natural nanotechnology for quantum experiments [3]. We ask what needs to be done to prepare, diffract, interfere and detect intact neutral vitamins, antibiotics, polypeptides or proteins [3-5]?  Answers to these questions open the path for quantum interference as a metrological tool, where the emerging density fringe pattern serves as a nanoruler that can be read with high precision and a force sensitivity < 10-26 N. Optical phase and photo-depletion beam splitters allow us addressing a plethora of organic particles in a universal way. This enables measurements of electronic [6], optical [7-9] or dynamical [10] molecular properties.
