Summary: | In this work, a uniform multiscale TiO2 nanorod array is fabricated to provide a “multi-scale interacting platform” for cell capture, which exhibits excellent capture specificity and sensitivity of the target cells after modification with bovine serum albumin (BSA) and DNA aptamer. After studying the capture performance of the BSA-aptamer TiO2 nanorod substrates and other nanostructured substrates, we can conclude that the multisacle TiO2 nanorod substrates could indeed effectively enhance the capture yields of target cancer cells. The capture yield of artificial blood samples on the BSA-aptamer TiO2 nanorod substrates is up to 85%–95%, revealing the potential application of the TiO2 nanorods on efficient and sensitive capture of rare circulating tumor cells. |
