CHE SIGNIFICA MICROBUBBLES IN INGLESE
Le microbolle
I microbubbles sono bolle di diametro inferiore a un millimetro, ma più grandi di un micrometro. Sono utilizzati nella diagnostica medica come agente di contrasto per l'imaging ad ultrasuoni. Il gas riempito, ad es. Aria o perfluorocarburi, i microbubbles oscillano e vibrano quando viene applicato un campo di energia sonica e può riflettere onde di ultrasuoni. Questo distingue i microbubbles dai tessuti circostanti. In pratica, poiché le bolle di gas in liquido mancano di stabilità e quindi si dissolvono rapidamente, i microbubbles devono essere incapsulati con un guscio solido. La copertina è costituita da un lipide o da una proteina come i microbubbles di Optison che sono costituiti da gas perfluoropropano incapsulato da una conchiglia di albumina. Microbubbles possono essere utilizzati per la consegna di farmaci, la rimozione del biofilm e gli scopi di trattamento delle acque / acque reflue. Sono anche prodotte dal movimento dello scafo di una nave attraverso l'acqua, creando uno strato di bolle; Questo può interferire con l'uso del sonar a causa della tendenza dello strato ad assorbire o riflettere onde sonore.
definizione di microbubbles nel dizionario inglese
La definizione di microbolle nel dizionario è un mezzo di contrasto utilizzato con gli ultrasuoni, costituito da minuscole bolle di gas introdotte nel sistema vascolare o dalle tube di Falloppio per migliorare le immagini ottenute.
