Polarity Index Dependence of M13 Bacteriophage-based Nanostructure for Structural Color-based Sensing

Color sensor systems based on M13 bacteriophage are being considerably researched. Although manystudies on M13 bacteriophage-based chemical sensing of TNT, endocrine disrupting chemicals, and antibioticshave been undertaken, the fundamental physical and chemical properties of M13 bacteriophagebasednanostructures require further research. A simple M13 bacteriophage-based colorimetric sensor wasfabricated by a simple pulling technique, and M13 bacteriophage was genetically engineered using a phagedisplay technique to exhibit a negatively charged surface. Arrays of structurally and genetically modifiedM13 bacteriophage that can determine the polarity indexes of various alcohols were found. In this research,an M13 bacteriophage-based color sensor was used to detect various types of alcohols, including methanol,ethanol, and methanol/butanol mixtures, in order to investigate the polarity-related property of the sensor. Studies of the fundamental chemical sensing properties of M13 bacteriophage-based nanostructures shouldresult in wider applications of M13 bacteriophage-based colorimetric sensors.
