WebAs the surface is slightly hydrophilic, the maximum binding capacity for a glycoprotein (antibody) will be lower compared to the hydrophilic surface. This will mean that the maximum binding capacity for IgG is less than 650ng/cm 2. The immobilization conditions should be calculated from the pI of the molecule that will be coated onto the surface. WebBharathidasan et al. (208) studied the role of fluorinated graphene oxide in making superhydrophobic and oleophobic surfaces by varying the work of adhesion and surface free energies. The work of adhesion ( W) is the work needed to split the unit area of two phases in contact and given by the Young–Dupré equation.
