Abstract:The chromatic transition from blue
to red in polydiacetylene (PDA)
membranes can be used for optical sensing in various applications
ranging from use as chemosensors to the quality control of foods and
medicines. The preparation of PDAs embedded in poly(vinyl alcohol)
(PVA) can be considered one of the simplest and most viable methodologies
for obtaining membranes with colorimetric responses. However, it is
still a scientific challenge to understand how the polymeric matrix
affects the chromatic transition of… Show more
“…21,36 Vesicular PDA solutions can be combined with soluble polymers to fabricate films by a solution casting method. 40,41,48,70 Alternatively, non-vesicular PDA films can be fabricated using forcespinning 43 or electrospinning 35,71 techniques. Polymer films have superior mechanical properties than gels for inclusion in food packaging.…”
Polydiacetylene (PDA) sensors have been developed as food management tools due to their convenient colorimetric signal, low cost, versatility, and ability to be incorporated into food packaging materials and devices....
