Current cancer diagnostic methods are challenged by low sensitivity, high false positive rate, limited tumor information, uncomfortable or invasive procedures, and high cost. Liquid biopsy that analyzes circulating...

Exosomes, important indicators of health conditions, are cell-derived vesicles that are present in blood and urine. A rapid analysis by biosensors helps...

Sensitive and selective detection of microRNAs (miRNAs) in cancer cells derived exosomes have attracted rapidly growing interest owing to their potential in diagnostic and prognostic applications. Here, researchers from the Fujian Agriculture and Forestry University design a ratiometric electrochemical biosensor ...

Recently, biological roles of extracellular vesicles (which include among others exosomes, microvesicles and apoptotic bodies) have attracted substantial attention in various fields of biomedicine. Here, researchers at Semmelweis University investigated the impact of sustained exposure of cells to the fluoroquinolone ...

Extracellular vesicles (EVs) are abundant in various biological fluids including blood, saliva, urine, as well as extracellular milieu. Accumulating evidence has indicated that EVs, which contain functional proteins and small RNAs, facilitate intercellular communication between neighbouring cells, and are critical ...
