Study of Sweet-Sensitive Taste Sensor with Lipid/Polymer Membranes

A sweet-sensitive taste sensor was investigated with potetiometric measurement.The transducer was a lipid/polymer membrane composed of tetradodecylammonium bromide,di-n-octylphenylphosphonate and polyvinyl chloride,which surface was modified with polyphenol and the solvent 30% EtOH,100 mmol/L KC1 and 10 mmol/L KOH.Balancing hydrophobic/ hydrophilic property and charge density on the membrane surface was susceptible to sensitivity for sweetener.Interaction between the membrane and sweet taste substances such as sucrose was detected as membrane potential change.

Balancing hydrophobic/ hydrophilic property and charge density on the membrane surface was susceptible to sensitivity for sweetener. Interaction between the membrane and sweet taste substances such as sucrose was detected as membrane potential change.
