Marietta Blau entwickelte fotografische Kernemulsionen, die die Abbildung und präzise Messung hochenergetischer Kernteilchen und ihrer Wechselwirkungen ermöglichten und damit das Gebiet der Teilchenphysik zu ihrer Zeit maßgeblich vorantrieben.

Ihre Methode der Kernemulsionen wurde von Cecil Powell in Bristol ab 1938 in großem Stil weiterentwickelt. Wie Marietta Blau untersuchte er die kosmische Strahlung und entdeckte damit neue Elementarteilchen, wofür ihm 1950 der Nobelpreis für Physik verliehen wurde. Marietta Blau, mehrmals für den Nobelpreis vorgeschlagen und vom Nobelpreiskomitee für ihre Arbeiten zwar gewürdigt, durfte die Früchte ihrer bahnbrechenden Forschung nicht ernten.
