Sensors inorganic

Preprocessed polymer films are synthesized and shaped by extrusion, stretched into sheet forms, and covered by metal film separately from the sensor structures. They can then be attached (typically by gluing) to inorganic sensor surfaces.

High-temperature/low-pressure inorganic digestions are an area of application that has benefited from recent advances in vessel and sensor design. The inert properties of Teflon and its resistance to acid attack make it the material of choice for microwave pressure-vessel construction. Improved commercial systems offer additional safety precautions and improved facilities for pressure and/or temperature control. Also, the distribution of microwave radiation inside the oven cavity is fairly homogeneous. Low-pressure systems allow decomposition temperatures of about 180 °C. However, for many matrices, such temperatures are not sufficient to guarantee the complete ashing of thermoresistant sample components. 

Recently, Astruc et al. [189] reported novel amido-ferrocene dendrimers (e.g., 91) which were shown to act as supramolecular redox sensors for the recognition of small inorganic ions (Fig. 41). It was further observed that as the den-drimer generation number increased the sensitivity to the guest molecules also increased as observed by cyclic voltammetry experiments.

In addition, the development in sensor materials opens a number of new possibilities, such as incorporation of organic and biochemical specific sites into inorganic matrices prepared by the sol-gel process.
