Dosimetric gelator probes and their application as sensors

Supramolecular gels formed by the self-assembly of organic molecules are useful in many areas from materials to medicine. Of different applications, exploitation for visual detection analytes is a fairly recent trend gel chemistry. Most gel-based sensors rely on non-covalent interactions between gelator and added chemical therefore, often suffer less selectivity long response time. In this context, dosimetric probes superior other with high fast Unlike binding sites, gelators typically contain reaction centre undergo specific selective an analyte resulting either formation or rupturing covalent bonds. review, we provide up-to-date report various reaction-based systems applied sensing analytes. We elaborately discuss concept, design principles, properties, mechanisms such gelators. also highlight limitations, challenges, necessity further exploration domain.
