연구 분야: Artificial Intelligence

학회: Optical Memory and Neural Networks

The paper presents results of the use of convolutional neural networks for the development of a multimodal photoluminescent nanosensor based on carbon dots (CD) for simultaneous measurement of the number of parameters of multicomponent liquid media. It is shown that using 2D convolutional neural networks allows to determine the concentrations of heavy metal cations Cu2+, Ni2+, Cr3+, anions and pH value of aqueous solutions with a mean absolute error of 0.29, 0.96, 0.22, 1.82 and 0.05 mM, respectively. The resulting errors satisfy the needs of monitoring the composition of technological and industrial waters.
