Fluorescence-producing reactions powder

Analytical Use of Fluorescence-Producing Reactions of Lipid- and Carbohydrate-Derived Carbonyl Groups with Amine End Groups of Polyamide Powder... 

Chemical Characteristics of the Oxidative Fluorescence-Producing Reaction and Presumptive Implication of Malonaldehyde The reaction producing measurable fluorescence on polyamide powder can be carried out in the gas phase by exposure to the volatiles from oxidizing polyunsaturated lipids, whether acids, esters, triglycerides, or phosphatides. It can be also carried out within either the oil phase or a water emulsion, and, as noted above, it can be followed in the vapor above an emulsion, providing the pH is 5.5 or below. 

This is a rapidly developing field. Analytical procedures can be established by several methods specie fluorescence fluorescence quenching chemically induced fluorescence (e.g., chelation of non-fluorescent metal ions with fluorescent ligands) and enzymic reactions that produce fluorescent products.Sample concentrations and identities can be determined in solution, on powders, or on glasses.
