Abstract
Fast monitoring and control quality of food products become increasingly important for public health Among foodborne pathogenic microorganisms bacteria are the most common foodborne pathogens in which the currently used methods are time consuming labourintensive and costly This work aims to develop a new biochip potentially used for an assessment of bacterial contamination on food product An assessment for bacterial detection employs simple FTIR spectroscopic analysis with a complimentary surface characterization by SEM technique The biochip based on carboxylic acid functionalized polyurethane PU film was synthesized for bacterial detection in particular Salmonella Typhimurium The PU in this study was synthesized from the reaction of the alcohol groups of hydroxyl telechelic natural rubber based oligomer with the isocyanate groups of 24toluene diisocyanate The carboxylic acid functional group was incorporated into the PU chain by addition of dimethylol propionic acid as a chain extender during PU preparation The PU film having different degree of carboxylic acid was explored for the detection of S Typhimurium The structural and morphological changes of the PU film after loading of the bacteria were successfully detected using ATRFTIR and SEM respectively The PU film developed is considered a rapid tool for S Typhimurium detection and has a potential application for rapid food control qualityThe authors would like to thank partially support from the French Embassy in Bangkok throughout the FrancoThai Hubert Currien Cooperation Program n°20596QA in Higher Education and Commission of Higher Education Ministry of Education Thailand The scholarship for T PengUbol from Royal Golden Jubilee PhD Program Thailand Research Fund was very much thankful
