Isolation of Cancer Cells from Liquid Biopsies Using 3D-Printed Affinity Devices

Abstract

Liquid biopsies are examination procedures for deciding the grouping of malignant growth cells tracked down in samples of blood and other body fluids. Liquid biopsies are likewise significantly less intrusive than tissue biopsies as they just require small amount of blood or body fluids from the patient. With the utilization of microfluidics, cancer cells can be isolated from the fluid biopsy and achieve early diagnosis. 3D printing is turning out to be progressively well known for microfluidic devices creation. 3D printing has shown multiple advantages compared to traditional microfluidic devices production, including effortless large-scale manufacturing of precise copies, the fuse of new materials, and execution of additional complicated or drawn-out plans that are hard to execute in conventional microfluidic devices. Combining 3D printing with microfluidics makes for a relatively inexpensive analysis of liquid biopsies with a chip that can be more advantageous to use over traditional microfluidic chips. In this chapter, a method for affinity-based separation of cancer cells in a liquid biopsy using a 3D microfluidic chip will be discussed, along with the rationale behind the method.
