O QUE SIGNIFICA MICROBUBBLES EM INGLÊS
Microbubbles
As microburbujas são bolhas com menos de um milímetro de diâmetro, mas maiores que um micrometro. Eles são usados em diagnósticos médicos como um agente de contraste para imagens ultra-sonográficas. O gás cheio, e. ar ou perfluorocarbono, microbolhas oscilam e vibram quando um campo de energia sônica é aplicado e pode refletir ondas de ultra-som. Isso distingue as microburbujas dos tecidos circundantes. Na prática, porque as bolhas de gás em líquido não possuem estabilidade e, portanto, se dissolvem rapidamente, as microbolhas devem ser encapsuladas com uma concha sólida. O invólucro é feito a partir de um lípido ou uma proteína, tais como microbolhas Optison que consistem em gás perfluoropropano encapsulado por um invólucro de albumina de soro. Microbubbles podem ser usados para entrega de medicamentos, remoção de biofilmes e tratamento de águas / águas residuais. Eles também são produzidos pelo movimento do casco de um navio através da água, criando uma camada de bolha; Isso pode interferir com o uso de sonar devido à tendência da camada de absorver ou refletir ondas sonoras.
definição de microbubbles no dicionário inglês
A definição de microbolhas no dicionário é um meio de contraste usado com ultra-som, consistindo de pequenas bolhas de gás introduzidas no sistema vascular ou trompas de Falópio para melhorar as imagens obtidas.
