This review provides an overview of the latest developments using small-molecule-based ratiometric fluorescent sensors designed for cadaverine detection.
This paper highlights the use of conjugated organic materials to construct sensors for the detection of biogenic amines released from decomposing food stuffs.
Structural deformation is noticed upon protonation in a symmetrically substituted thiophene-anthracene linked π-conjugate bearing two terminal pyridyl units. Such a deformed molecule exhibits emission change and detect polyamines and nicotine.
Cyanoacrylic acid-based fluorophore shows concentration-based selective response to aliphatic biogenic amines and thus, is demonstrated to monitor spoilage of protein-rich food items progressively through emission shifts visible to the naked eye.
A ratiometric fluorescent sensor for eight kinds of biogenic amines was established by facile mixing of pH-responsive carbon dots and Rhodamine B.
