Abstract

The opportunity to control of ammonia is important in different application areas such as environmental gas analysis, automotive and chemical industry, medical diagnostics, etc. Some monitoring systems require very low detection limits (for example, 50 ppb for diagnostic breath analysis).
Ink-jet printing is known to be one of the most promising methods for controlled deposition of functional materials. For example, arrays of the colloidal photonic crystals may be directly fabricated using an ink-jet printing. Development of optical sensor materials based on micro and nanoparticles with dyes immobilized on their surface was pointed out to be very important for further optical chemical sensors and electronic nose systems progress. It is obvious that a wide range of materials can be created by combining different dyes, particles and methods of immobilization and that a chemical modification of the indicator dye and the surface of the particle permit functional characteristics of material to be tailored for a specific analyte or a group of analytes.
Many features make fluorescence one of the most powerful transduction. Therefore, an array of sensor elements each of which represents an ensemble of fluorescent functional micro- or nanoparticles is a perspective transduction platform.
In this study, the results of studying fluorescent sensor microarrays fabricated by inkjet printing and application of the arrays to ammonia detection are presented.
