Ultrafast Laser-Induced 1T′/2H-MoTe2 Nanopattern with Au-Nanoclusters for Raman Monitoring of Cellular Drug Metabolism

array provides a powerful SERSome (comprising multiple SERS spectra) platform for therapeutic drug monitoring, by which we successfully identified the metabolic behaviors of living gastric adenocarcinoma cells administered with two drugs, i.e., capecitabine, oxaliplatin, and their combination. The present work establishes opportunities for creating a highly ordered nanopattern array for ultrasensitive SERSome analysis of cell metabolism in cancer therapy.
