The single signal output from the tannic acid (TA) sensor can lead to false positive results. Therefore, designing the detection strategy of dual signals of colorimetric and temperature is important for accurate detection and is key to further construction of highly sensitive sensors. In this work, through a self-assembly strategy, we synthesized rosmarinic acid-cerium (RA-Ce) nanoparticles with excellent peroxidase-like activity. The RA-Ce based sensor enables fast and sensitive quantification of TA by detecting color and temperature changes with commendable linearity across the 0.05-3.5 mu M...
