A group of researchers at the Chinese Academy of Sciences has proposed a new electrochemical biosensor for early cancer diagnosis.
Based on 2D MXene membranes decorated with hierarchical Au nanoarrays, the biosensor detects and identifies target exosomes, potentially detecting cancer at an early stage as well as providing monitoring of metastatic cancer cells.
Exosomes are small extracellular vesicles that are derived from tumour cells.
The new electrochemical biosensor demonstrated satisfactory reproducibility and high sensitivity in sensing exosomes.
