Matter-wave interfererometers generate nanostructures on molecular beams that can be read with nanometer accuracy and therefore be used for highly sensitive force measurements, from which one can deduce a plethora of properties of individualized complex molecules.<ref>{{Citation |last1=Gerlich |first1=Stefan |title=Otto Stern's Legacy in Quantum Optics: Matter Waves and Deflectometry |date=2021 |work=Molecular Beams in Physics and Chemistry: From Otto Stern's Pioneering Exploits to Present-Day Feats |pages=547–573 |editor-last=Friedrich |editor-first=Bretislav |place=Cham |publisher=Springer International Publishing |language=en |doi=10.1007/978-3-030-63963-1_24 |isbn=978-3-030-63963-1 |last2=Fein |first2=Yaakov Y. |last3=Shayeghi |first3=Armin |last4=Köhler |first4=Valentin |last5=Mayor |first5=Marcel |last6=Arndt |first6=Markus |editor2-last=Schmidt-Böcking |editor2-first=Horst|doi-access=free |bibcode=2021mbpc.book..547G }}</ref>
