A novel self-assembled monolayer (SAM) coated microcantilever for low level caesium detection

We report a new sensor concept based on an ion-selective SAM modified microcantilever which can detect caesium ion concentrations in situ in the range 10(-11)-10(-7) M and shows potential for use in developing a new family of real time in situ metal ion sensors with high sensitivity/selectivity and low cost, for chemical and biological applications.
