1 Retraction

This article [1] has been retracted on request of the corresponding author due to a concern regarding the utilization of TGA for determining end-grafted polymer chain density using these relatively low surface area substrates (as opposed to higher surface area systems like nanoparticles). Despite the proper controls being done and the data being handled properly, it is evident that the mass change on these surfaces may be below the limit of the sensitivity of TGA. The article will be corrected and resubmitted for another peer review. Please note that the other experiments (ellipsometry and protein adsorption) were conducted using well established techniques and correctly handled and represented within this article (with specified limitations acknowledged appropriately). It is important to clarify that honest error, and not an ethical issue, was the cause for the retraction.
