in the liver and spleen , organs with discontinuous ( sinusoidal ) capillaries , ultrastructural and cell fractionation studies revealed that small ( 300- to 800-a diameter ) , sonicated , unilamellar liposomes were more efficient in penetrating liver sinusoids to interact with hepatocytes than were large ( 0.5- to 10-micrometers ) multilamellar liposomes .
