“…Meir et al [26] constructed agarose-embedded chromatic films to obtain color changes and fluorescence transformations in response to bacterial growth. Ma et al [27] developed a film using polydiacetylene with mannose assembled by LangmuirBlodgett technology to detect E. coli. Nevertheless, none of these studies the film could be used as intelligent packaging due to the complexity of the techniques and the features of the films.…”

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.

“…According to Ma et al (2003), specific interactions between biological molecules and receptors may serve to alter the side chain conformation, causing the change from acetylene to butatriene. This transformation increases the energy gap that causes the change in the visible absorption spectra, resulting in the observation of the red form.…”

“…The films produced were horizontally transferred to a glass surface modified with octadecyltrichlorosilane, which makes it hydrophobic. Hydrophobic layers were used in other studies to modify surfaces (Gaboriaud et al 2001;Guo et al 2007;Ma et al 2003;Scindia et al 2007;Volinsky et al 2007). …”

“…The ganglioside G Tb1 was incorporated into a PDA film that was able to detect the botulinum toxin (Charych et al 1996). Mannose derivatives have been used in various studies as a ligand for E. coli (Ma et al 2003;Su Fig Zhang et al 2005). The most probable manner in which the film interacts with E. coli is through the adsorption of E. coli on the film surface using its pili.…”

“…Ma et al (2003) monitored the colorimetric response of PDA mannose-containing films in the presence of E. coli using visible absorption spectroscopy. On the other hand, the colorimetric transition of phospholipids/PDA films in the presence of different bacteria was measured using a colorimetric image analysis methodology, and the colorchange values were calculated using mathematical software (Scindia et al 2007).…”

Biosensors offer the potential for real-time pathogen detection. Polydiacetylene (PDA) is an ideal choice for use as a sensor due to its unique optical properties. PDA molecules can form thin films or vesicles that change color from deep blue to red in response to different stimuli, like temperature, pH, and the presence of biological molecules. PDA films and vesicles have been proven to be promising devices for the detection of bacteria and bacterial toxins. Langmuir troughs (for films) and microcalorimetry (for vesicles) are among the many techniques used to characterize PDA films and vesicles. In order to enable more applications of PDA films, it is imperative to elucidate and gain a deeper understanding of the molecular interactions associated with their color change. In addition, it is necessary to transfer the PDA film onto a solid support like plastic in order to incorporate PDA biosensors into an intelligent packaging system. Through the use of such a system, consumers can monitor food quality, thereby preventing foodborne outbreaks. In this review, we discuss the formation of PDA films and vesicles, their characteristics, and their potential applications as biosensors. The possibility to incorporate PDA biosensors into an intelligent packaging system to be used in the food industry is also explored.
