A reversible, colorimetric, pH-responsive indole-based hydrogel and its application in urea detection

A new type of pH-responsive indole-based (4-HINF) hydrogel, fabricated by a sol–gel method, was utilized as a platform for colorimetric detection of urea in aqueous solution. The colorimetric sensor was established by virtue of the synergistic effect of cation–π interaction and hydrogen bonding with...
