Albumin carbon coated surface

Acetylcholineesterase and choline oxidase Carbon-fiber micro-electrode for determination of ACh and choline, mounted in a glass capillary tube. Enzyme was immobilized on the surface of the carbon fiber with albumin. Electrode was dip-coated with Nafion. Evaluation of selectivity and dynamic range, at a fixed potential of 1.2 V versus Ag-AgCl. Calibration graph for ACh and Ch was rectilinear between 0.1 and 3mM. Interference from ascorbic acid was not observed in the range 0.1 to 0.3 mM. [79]... 

One interesting feature of porous Si membranes is the possibility to easily modify their surface chemistry (Stewart and Buriak 2000). The handbook chapter Silicon-Carbon Bond Formation for Porous Silicon reviews the techniques and surface chemistries available. In order to prevent undesired adsorption of proteins on the membranes (ultimately clogging the pores), it is also possible to coat them with a thin layer of polyethylene glycol (PEG) (Zhang et al. 1998 Sharma et al. 2003). PEG chains covalently linked to Si decrease the adsorption of albumin, IgG, and fibrinogen by 76, 82, and 64 %, respectively, as compared to untreated Si.
