Complex Fluids Flow at Meso and Nano Scales and Its Implications in Biological Structures Behaviors

Complex fluids are a very favorable medium for the appearance of instabilities that imply both chaos and self-structuring through generation of ordered complex structures. In such context, the standard and "exotic" properties of complex fluid flow at meso and nano scale can be highlighted. As a consequence we analyze possible implications of complex fluids behaviors in blood flow dynamics. Moreover, we can say that fractal physics can explain the initiation phase of arteriosclerosis. Furthermore, our model imposes a redefinition of "good" and "bad" cholesterol, suggesting that they should be replaced by the following notions: specific cholesterol particles, associated with a certain non-differentiable curve, that have a major endothelial impact and specific cholesterol particles which have none or low endothelial impact.
