Abstract

La présente invention concerne un procédé destiné à la mesure quantitative de contenu particulaire à l'aide d'une imagerie à l'état hydraté telle qu'une cryotem. L'invention concerne également un échantillon (100) de particules pseudo-virales (vlp) ou de particules virales. De préférence, l'échantillon (100) est rapidement congelé dans un liquide cryogénique à une température cryogénique. Selon l'invention, le contenu particulaire de chaque vlp dans l'échantillon congelé à température cryogénique est obse
