Phage PVP-SE1 as Tool Recognition in Polydiacetylene to Produce Intelligent Packaging
Journal Title: Journal of Food Chemistry and Nanotechnology - Year 2017, Vol 3, Issue 2
Abstract
Polydiacetylene (PDA) compound has unique chromatic properties when embedded in methylcellulose base. Therefore, this could be used as intelligent packaging. PDA exhibits blue-to-red color transition under certain stimuli, which was caused by alterations in PDA conjugation length backbone. For a specific color modification, bio-recognition tools were covalently linked with PDA. In this work, a broad-spectrum virulent phage (PVP-SE1) was used as a biorecognition element to detect Salmonella cells due to PDA color change. A series of experiments were performed to monitor colorimetric response. Consequently, chromatic immunoassay could be significant in increasing potential applications of PDA intelligent packaging.
