In situ microspectroscopic monitoring within a microfluidic reactor

Abstract

A novel in situ microspectroscopic monitoring system was developed, coupling a microspectrophotometer with a microscope and optical elements, for real time monitoring of chemical reaction progress within a microfluidic reactor by absorbance measurements. The formation process and rapid changes in size and shape of silver nanoprisms were successfully detected and reveal that these changes take place in a very short section of the microreactor.
