Figure Lengend Snippet: Typical immunocapture microfluidic device. ( A ) Using aptamer cocktail to enrich CTCs in patients with lung cancer; reproduced from Reference , with a permission from Small . ( B ) Herringbone microfluidic probe. (a) The schematic shows the working process of HB-MFP, in which blood is injected through the central aperture and exits through the peripheral aperture. (b) The tip surface of 3D-printed HB-MFP. (c,d) Specifically showing the surface structure in (b); reproduced from Reference , with permission from Advanced Materials Technologies . ( C ) Scheme shows the structural composition and working principle of the Ap Octopus Chip. The chip captures CTCs, using the synergistic manner of multivalent aptamers formed by AuNP-SYL3C and a triangular DLD array design. In the sequencing curves, green, red, blue and black represent adenine (A), thymine (T), cytosine (C) and guanine (G); respectively; reproduced from Reference , with permission from Angewandte Chemie International Edition . ( D ) The process of capturing CTCs using aptamer modified AuNP surfaces; reproduced from Reference , with permission from ACS Nano .
