openQCM Wi2 has a wide area of practical applications. It is useful for monitoring the real­time variations of thin film deposition in any ambient conditions. Then QCM is very effective in measuring adsorption-­desorption of molecular layers, SAM self­assemblied monolayer, swelling rates, hydratation of thin film. It is also useful for sensing molecular structural changes caused by chemical reactions on its surface. QCM could be used as a tunable gas sensor and for monitoring the aerosol deposition in ambient conditions. The applications in liquid environment show enormous potentiality. QCM is very effective in measuring binding events on functionalized surface, such as antigen­-antibody binding and protein-­protein interactions. It is a powerful tool in life sciences, being able to sense DNA hybridization and specific drug compounds. These are just a few example of the possible applications of quartz crystal microbalance for your own research. The real question is: What you can do with an entire laboratory in the palm of your hand ?
