Formaldehyde sensor produced by Hussain et al., with several gases at 100 ppm. The graph is striking but somewhat superfluous as it simply shows formaldehyde at 100% and all other VOCs at 0%. MIP films (red) and nanoparticles (yellow) were prepared using an approximately 1:1:1:2 template-monomer-monomer-crosslinker ratio in methanol and dimethylformamide. Films were spin-coated directly onto the QCM electrode, while nanoparticles were first precipitated by addition of acetonitrile. Reproduced with permission [21].
