MicroRNA exhibits differential expression levels in cancer and can affect cellular transformation, carcinogenesis metastasis. Although fluorescence techniques using dye molecule labels have been studied, label-free molecular-level quantification of miRNA is extremely challenging. We developed a surface plasmon resonance sensor based on two-dimensional nanomaterial antimonene for the specific detection clinically relevant biomarkers such as miRNA-21 miRNA-155.
