Imaging γ-Glutamyltranspeptidase for tumor identification and resection guidance via enzyme-triggered fluorescent probe

Development of high selectivity, accurate targeted and noninvasive fluorescent probe for monitoring specific enzyme activity associated with the tumor is urgent needed for early diagnosis of cancer and clinical fluorescence interventional resection guidance treatment. Owing to the invasion of malignant tumor cells, tumor cells are mixed with normal cells in the actual tumor location, which make it quite difficult for clinician to diagnose early...
