Biomaterial-induced alterations of human neutrophils under fluid shear stress: scanning electron microscopical study in vitro.

abstract：:Translation of micelles from the laboratory to the clinic is limited by a poor understanding of their in vivo fate following administration. In this paper, we establish a robust approach to real-time monitoring of the in vivo stability of micelles using Förster Resonance Energy Transfer (FRET). This characterization m...
