Web1 de jul. de 2024 · Hydrophobicity measurement. The hydrophobicity of the control and polymer-coated wood samples were evaluated by measuring water static contact angle (CA). The CA was measured at room temperature by a drop shape analyzer (KRÜSS, DSA25, Germany). The CA was recorded at 30 s after a water droplet (5 μl) was put on … Web5 de jan. de 2024 · Here, we introduce a physics-based approach to describe hydrophobicity in terms of the hydration free energy using grid inhomogeneous solvation theory (GIST). We apply this method to assess the effects of starting structures, conformational sampling, and protonation states on the hydrophobicity of antibodies.

WebThe charge and hydrophobicity differences between AAV2 and AAV8 are related to the distribution of charge on the surface and not the total charge. We propose that the presence of nucleic acids inside the capsid causes minor but measurable changes in the capsid structure that lead to measurable surface changes in charge and hydrophobicity.
