Human serum albumin (HSA) represents a promising candidate that binds a wide range of compounds with different physicochemical characteristics. In 2007, with Abraxane®, a first polymeric nanoparticle formulation consisting of this material has been
  • the present study, nanoparticles consisting of HSA were formed by ethanolic desolvation [9]. These nanocarriers were used matrix system for the encapsulation of USPIO. USPIO have been efficiently applied as contrast agents for magnetic resonance imaging and allow the tracking of nanoparticles in vivo

The midpoints of the binding transition, which quantifies the affinity of HSA toward the NP, were observed to differ by almost

In our original FCS study [45], we investigated the adsorption of human serum albumin (HSA) onto carboxyl-functionalized, polymer-encased iron platinum nanoparticles (Fe–Pt NPs) with a hydrodynamic radius, RH, of 5–6 nm. We prepared HSA solutions of different concentrations in

Recently, we have used quantitative fluorescence microscopy, especially fluorescence correlation spectroscopy (FCS), to study protein adsorption of human serum albumin (HSA) on polymer-coated FePt NPs with an

We found that, at concentrations typically found in blood serum, ~20 HSA molecules adsorb as a monolayer of ~3.3 nm
