A Litmus‐Type Colorimetric and Fluorometric Volatile ...

2013-02-18· Inkjet-printed paper-based volatile organic compound (VOC) sensor strips imaged with polydiacetylenes (PDAs) are developed. A microemulsion ink containing bisurethane-substituted diacetylene (DA) monomers, 4BCMU, was inkjet printed onto paper using a conventional inkjet office printer. UV irradiation of the printed image allowed fabrication of blue-colored poly-4BCMU on the …

Colorimetric Sensors and Sensor Arrays - ScienceDirect

2019-01-01· Introduction to Colorimetric Sensors. A sensor is a device that transforms information about a chemical or physical property of the system into an analytically useful signal. 1 Interactions between the medium and the sensor leading to change in optical properties, or in other words, leading to optical signals that can be read and interpreted, are often utilized for the creation of optical ...

Smartphone-based VOC sensor using colorimetric ...

Owing to a unique colorimetric (typically blue-to-red) feature upon environmental stimulation, polydiacetylenes (PDAs) have been actively employed in chemosensor systems. We developed a highly accurate and simple volatile organic compound (VOC) sensor system that can be operated using a conventional smartphone. The procedure begins with forming an array of four different PDAs on …

Study of polydiacetylenes and rhodamine-800 mixed film at ...

2020-01-08· Here, we report the mixing behaviour of diacetylene monomer 10, 12-tricosadiynoic acid (TCDA) and rhodamine-800 (Rh8) using Langmuir–Blodgett (LB) technique. The presence of Rh8 affected the structures, phase behaviour as well as colorimetric properties of TCDA in the mixed films at air–water interface and onto solid support. The mixed LB films having TCDA molefraction ≥ leads …
