Nanoparticles in biological media adsorb proteins onto their surface and generate protein coronas. The protein affinity toward nanoparticle surfaces potentially depends on the constituent amino acid side chains which are exposed to the solution and available for interaction. Therefore, studying the adsorption of individual amino acids on nanoparticle surfaces can provide valuable insights into the overall evolution of the protein corona. In the current study, the surface adsorption of several amino acids on TiO<sub>2</sub> nanoparticles at different pHs is studied from both macroscopic and molecular perspectives. ATR−FTIR spectroscopy and QCM-D analysis are used to determine and quantify adsorption mechanisms.
