New paper just online from Vaidehi, where we show that stealth and low-fouling attributes are not the only important parameters determining hemocompatibility; coagulation also matters! We find that PEG nanoparticles induce coagulation responses in human blood, and that this can be overcome through exerting control over the biomolecular corona formation at the bio-nano interface. Excellent work and well done to Vaidehi!
