The incorporation of functionalised carbon nanodots within a novel low molecular weight salt hydrogel
derived from 5-aminosalicylic acid is reported. The carbon dots result in markedly enhanced gelation
properties, while inclusion within the hydrophobic gel results in a dramatic fluorescence enhancement
for the carbon nanomaterials. The resulting hybrid CD gels exhibit a useful sensor response for heavy
metal ions, particularly Pb2+.
