Gas Immunosensors

Antibodies against small molecules (haptens) can be readily prepared. It has been suggested that Ab against, for example, pesticide gas molecules can be immobilized on mass sensors and used for sensing of such gaseous compounds. 

What will be the major interferant in such scheme  

Assume that the hydrophobic bond is a major component of the binding interaction of the gas with the antibody binding site. What is the consequence for that type of chemical bond if performing this reaction is carried out in gas phase
