Abstract
Exosomes are a type of extracellular vesicles that contain constituents including proteins, DNAs, and RNAs of the cells that secrete them. Cancerous exosomes are potential biomarkers for cancer diagnosis. Biosensors are useful analytical tools for quantification of biomarkers and targeted molecules. An aptasensor uses the aptamer as the biorecognition element to bind to the target and is one main type of biosensors that is promising for exosomes analysis and clinical cancer detection. The assay described in this chapter allows for reliable, sensitive, and specific detection of cancer-derived exosomes using a colorimetric aptasensor that is promising for point-of-care testing.Entities:
