Improvement on alcohol Breath-Analyzer ethanol biosensor based on roselle-chitosan blend

This paper presents a study on designing of a breath-analyzer ethanol biosensor through vaporization technology. A roselle extract and chitosan smart gel were used to fabricate the bio-sensing material. Sol-gel electrochemical deposition method was used to coat a thin film of the sensing material bl...
