Under the links below you can find more information regarding the technologies used for the production of fluorescence based micro-sensors. The micro-sensors allow for the analysis of various parameters (e.g.: O2, pH, chloride, and temperature) in small spaces without the need for the meter to be in direct contact (e.g.: microfluidics, cell cultures, cell lines) by measuring changes in the fluorescence intensities or fluorescence lifetimes.
