The article "Understanding Protein Adsorption Phenomena at Solid Surfaces" by Rabe, Verdes, and Seeger provides a comprehensive review of the current understanding of protein adsorption processes. Protein adsorption is a critical process in various natural and biomedical processes, but it remains a complex and poorly understood phenomenon. The authors discuss recent advancements and new perspectives on protein adsorption, focusing on mechanistic aspects and their mathematical descriptions. They highlight the importance of experimental and computational strategies in advancing the field.
Key aspects covered include the influence of external parameters such as temperature, pH, ionic strength, and buffer composition on protein adsorption. The complex behavior of proteins, including structural rearrangements, cooperative adsorption, overshooting adsorption kinetics, and protein aggregation, are also discussed. The article emphasizes the role of protein properties, such as size, structural stability, and composition, in determining adsorption behavior. Surface properties, including surface energy, polarity, charge, and morphology, are also crucial factors.
The individual behavior of proteins at interfaces is explored, including their orientation and conformational changes. The ensemble behavior of proteins, such as the structure of the protein layer, lateral interactions, and cooperative effects, is analyzed. The concept of cooperative adsorption, where the adsorption of one protein can enhance the adsorption of others, is discussed, along with the phenomenon of overshooting adsorption kinetics, where adsorption rates peak before reaching saturation.
The article concludes by highlighting the need for further research to better understand and predict protein adsorption phenomena, emphasizing the importance of both experimental and computational approaches.The article "Understanding Protein Adsorption Phenomena at Solid Surfaces" by Rabe, Verdes, and Seeger provides a comprehensive review of the current understanding of protein adsorption processes.
