POSS® Sensors
In one line of products, hydrogen-bond acidic surface acoustic wave (SAW) sensor groups have been placed on POSS® cages. It has been shown that POSS® SAW sensors maintain better performance over time than conventional linear polymer SAW sensors. In order to collect the most chemical information, an array of SAW sensors must cover the full range of solubility, dipole-dipole, and hydrogen-bonding interactions. The detection of hydrogen-bond basic entities such as nerve agents and explosives using commercially available hydrogen-bond acidic SAW materials is now possible through use of POSS® SAW cages.

In another line of products, two-photon fluorophoric sensor groups have been placed on POSS® cages and used in remote detection. These fluorophores change their wavelength of emission in response to their chemical environment, and a set or array of these POSS® compounds can generate a unique fingerprint for a given analyte in solution, on surfaces or in cloud form. The array can be remotely interrogated by an ultrafast infrared laser, and can send information back to a remote fluorimeter. For a surface acoustic wave POSS® sensor reference, click here.
