Detection of the crystallization process of paracetamol with a multi-mode optical fiber in a reflective configuration. Sensors, 20(1), 871424-8220http://hdl.handle.net/10400.14/29297A configuration of a refractometer sensor is described with the aim of optically detecting the crystallization process of paracetamol. The developed sensing head is based on a conventional cleaved multi-mode fiber. The fiber tip sensor structure was submitted to contact with the liquid of interest (paracetamol fully dissolved in 40% v/v of ethanol/water) and the crystallization process of paracetamol, induced with continued exposure to air, was monitored in real time.engParacetamolCrystallizationMulti-mode optical fiberjournal article10.3390/s2001008785077287128PMC698273631877833000510493100087
