Single-cell detection by enhancement of fluorescence in waveguides for cancer diagnosis and therapy

Cancer is one of the most common diseases to threaten human health.If individuals are diagnosed with malignant tumors via a single cell,medical workers are greatly advantageous to early diagnose and intervene in malignant tumors therapy.In this paper,we propose a fluorescence detection map to rapidly distinguish whether the chromosomes of a cell are normal or abnormal by detecting the fluorescent intensity of a single cell.Herein,we draw a map from a single cell with an abnormal number of chromosomes that is monitored in real time.Moreover,this way offers precise and prompt detection of the surviving of cancer cells at or near the site of the tumor after treatments for cancer,which can achieve personalized cancer diagnosis and therapy.Therefore,cancer recurrences and metastasis can be effectively identified,utilizing this ultrasensitive detection method of an abnormal chromosome number.
