Protein adsorption on thermoplastic elastomeric surfaces: A quantitative mass spectrometry study

- Protein adsorption on tissue engineering surfaces quantified by mass spectrometry.
- Quantities in the range of 0.1-400 pmol/cm2 were detected by MALDI-ToF MS.
- Adsorption on nonpolar surfaces increases with protein and surface hydrophobicity.
- Amount adsorbed maximizes at the isoelectric point and decreases with protein size.
- Electrospun surface morphologies adsorb more protein than molded surfaces.
