	abstract = {Surface induced thrombus generation is a major clinical concern associated with vascular medical devices and implants. Here, we show that high graft density hydrophilic non-charged poly (N,N-dimethylacrylamide) (PDMA) brushes prevent the initiation of blood coagulation on synthetic surfaces. Using a multi-faceted analysis approach, we have identified that PDMA brushes greater than 0.27 chains/nm2 graft density showed this highly desired property. Non-specific protein adsorption is greatly reduced on high density brushes compared to bare surface as evident from isothermal titration calorimetry, gel electrophoresis, and proteomic analyses. We have identified approximately 129 proteins of various types on bare and PDMA brush coated surfaces at a range of surface concentrations. Thromboelastography, platelet activation, and aggregation analyses show that only high graft density brushes are neutral to blood coagulation. Since the polymer brush synthesis can be adapted to most currently used biomedical materials, these results have significant impact in the design of highly hemocompatible surfaces.},
