Abstract
The detection of hazard exposure is a current priority, including the detection of traces of explosive molecules in different environments like luggage storage rooms and public places, and is becoming a major requirement for homeland security. In the present study we carried out a preliminary investigation on the binding capacities of four forms of the lipocalin odorant- binding protein ( OBP) for the detection of explosive components such as diphenylamine, dimethylphthalate, resorcinol and dinitrotoluene. The experimental results, showing that OBP binds these compounds with affinity constants ranging between 80 nM and 10.6 mM, indicate that this protein can be used as a probe for the realization of a biosensor to sense explosive compounds.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
