Abstract
SE DESCRIBEN SUSPENSIONES DE MICROBURBUJAS DE GAS INMOVILIZADAS CON UN VEHICULO ACUOSO CONGELADO QUE CONTIENE LOS ADITIVOS Y ESTABILIZANTES HABITUALES. EL VEHICULO LIQUIDO ES FISIOLOGICAMENTE ACEPTABLE, LAS MICROBURBUJAS DE GAS INMOVILIZADAS SON MICROBURBUJAS UNIDAS POR UNA ENVOLTURA EVANESCENTE O UNA MEMBRANA TANGIBLE. LAS SUSPENSIONES, CUANDO ESTAN EN FORMA LIQUIDA, SON INYECTABLES Y UTILES COMO AGENTES DE CONTRASTE EN EL DIAGNOSTICO ULTRASONICO POR IMAGENES DE LA SANGRE Y EL TEJIDO DE LOS SERES VIVOS. LAS MICROBURBUJAS DE GAS SE INMOVILIZAN EN EL INTERIOR DEL VEHICULO AL CONGELAR UNA SUSPENSION DE MICROBURBUJAS CON UN TAMAÑO MEDIO INFERIOR A 50 {MI}M, PREFERIBLEMENTE ENTRE 2 Y 8 {MI}M, A UNA TEMPERATURA ENTRE -1 Y -76 GRADOS C Y MANTENIENDO ESTA TEMPERATURA DURANTE PERIODOS PROLONGADOS DE TIEMPO. LAS MICROBURBUJAS PUEDEN ESTABILIZARSE MEDIANTE UN SURFACTANTE, COMO UN FOSFOLIPIDO LAMELAR, O PUEDEN INCLUIR UNA MEMBRANA HECHA CON POLIMEROS NATURALES O SINTETICOS, O PROTEINAS. TAMBIEN SE DESCRIBE UN METODO DE ALMACENAMIENTO EN FRIO DE LAS SUSPENSIONES DE MICROBURBUJAS, ASI COMO SU USO.
