Abstract: Glycoproteins are closely associated with the occurrence of diverse diseases, and they have been used as biomarkers and therapeutic targets in clinical diagnostics. Currently, mass spectrometry has proven to be a powerful tool for glycoprotein analysis, but it is almost impossible to directly identify glycoproteins without the preparation and pretreatment of samples. Furthermore, biological samples, especially proteins, are damaged by this process. Herein, we describe a novel fluorescence nanosensor based on a molecularly imprinted spatial structure and boronate affinity that is well-suited for monitoring glycoproteins selectively. Results showed that the recognition performance of the nanosensor for glycoproteins was regulated by controlling the pH value and temperature. Moreover, the nanosensor was successfully applied to the detection of HRP in biological fluids. This study provides a facile and efficient fluorescence tool for glycoprotein detection in clinical diagnostics
