The aim is to develop a nanosensor for the quantitative detection of tyrosine in urine to aid in tumor screening.
Developed a nanosensor using nitrogen-doped graphene quantum dots (N-GQDs).
Focused on fluorescence-based detection of urinary tyrosine.
Evaluated the sensor's sensitivity and quantitative capabilities.
Successfully detected urinary tyrosine with high sensitivity.
Demonstrated potential value for tumor screening applications.
Abstract
