Materials and Experimental Setup

We have used apoenzymes as molecular-recognition transporters for binding and selective transportation of molecules without production of unwanted chemical reactions on reactants. Figure 24.10 shows the design of membrane consisting of microporous polymer membrane sandwiched between two thin films of polypyrrole [3]. The apoenzymes are physically trapped within the pores of the membrane and polypyrrole films. More details regarding the fabrication of the membranes, materials, and experimental setup can be found in the Ref. [3]. 

In summary, different investigators have obtained different results for the magnitude and sign of line tension by using different experimental approaches and materials. Unless the same materials and experimental setups are used, the comparison of the results are not sensible (98).
