Nanotextured substrates with immobilized aptamers for cancer cell isolation and cytology

Abstract

A comparison between glass slides, plain PDMS, and nanotextured PDMS functionalized with aptamers demonstrated that a 2-fold approach of using aptamers on nanotextured PDMS can be important for cancer cytology devices, and especially for the idea of a "lab-on-chip," toward higher yield in capture efficiency.
