A remarkably high signal-to-noise ratio may be anticipated to find minimal lysozyme in complicated serum samples.153 Hence, they limited the generation of autofluorescence with greater sensitivity toward the detection of biomarkers for utilization in biomedicine.153 Similarly, Y. Zhao et al. developed electrode-altering bismuth sulfide NCs for identifying cytokeratin 18, a biomarker for bladder cancer. This evidence concerns the gene KRT18 and urinary bladder cancer.
