Description 73-82
The present paper aims to study the complex oscillations at liquid-liquid interface while mimicking sensing mechanisms of smell-oscillations of electrical potential differences across a bipolar liquid membrane induced by different classes of olfactory agents, e.g. amines, alcohols, acids, aldehydes and esters, in vitro. A preliminary attempt was made to classify and quantify various smelling agents and thereby developing a smell sensor. The bipolarity was induced by introducing a cationic (cetyl pyridinium chloride) and anionic surfactant (sodium lauryl sulphate) along with the electrolytes like sodium and potassium chloride in the experimental set-up. The data obtained indicate that olfactory agents of different groups exhibit characteristically different frequency and amplitude.
