An ensemble of aptamers and antibodies for multivalent capture of cancer cells

Chem Commun (Camb). 2014 Jun 28;50(51):6722-5. doi: 10.1039/c4cc02002b.

Abstract

We developed an optimized ensemble of aptamers and antibodies that functions as a multivalent adhesive domain for the capture and isolation of cancer cells. When incorporated into a microfluidic device, the ensemble showed not only high capture efficiency, but also superior capture selectivity at a high shear stress (or high flow rate).
