About this collection
Liquid Biopsy, coined by Pantel and Alix-Panabières in 2010, originally referred to real-time analyses of CTCs in cancer. However, that term has since expanded to encompass the analyses of many other disease-related substances found in blood and other body fluids. Our goal is to highlight the new advances in this growing field with an emphasis on the interface between the technological advancements and high impact applications of liquid biopsy technologies. These would include manuscripts related to components that can be captured or characterized from blood such as circulating tumour cells, circulating nucleic acids and circulating extracellular vesicles. This on-going collection is collated by Thought Leaders Mehmet Toner and Stefanie Jeffrey and the Lab on a Chip Editorial Office.
