We recently reported preliminary results of an optical, disposable sensor to detect biodiesel (also known as Fatty Acid Methyl Esters or FAME) at low and high concentrations in diesel.1 The sensor is based on solvatochromism of the dye Nile Blue chloride in a thin film, leading to a color change from blue in diesel to pink in the presence of 0.5-200,000 ppm (20% v/v) FAME/biodiesel in diesel. We have recently studied the response of the sensor in the presence of potential interferences such as the anticorrosion agent DCI-4A, water, and the fuel dye additive Solvent Red 26. In addition, efforts have been made to couple the sensor with a portable visible spectrometer. The new studies will be presented. 1.
