Tungsten oxide may be applied in colorant sensor to differentiate edible colorant and toxic pigments. It means that the WO3 based sensor may be used for food safety assessment based on electrochemical detection of hazardous dyes in food. More details, please visit: http://tungsten-oxide.com/index.html It has been reported that tungsten oxide based micro and nanostructures as well as their 2-D integrated counterparts with appropriate surface modifications such as sensitization, coating of other semiconductors or growth of dingal groups have been examined…
