Abstract
In one aspect, methods of detecting tumor cells are described herein. In some embodiments, a method of detecting tumor cells comprises providing a device, the device comprising a substrate surface and a plurality of first aptamer probes attached to the substrate surface. The method further comprises contacting a plurality of cells with the plurality of first aptamer probes attached to the substrate surface; adhering one or more of the plurality of cells to the substrate surface; and measuring a non-uniformity parameter, a Hausdorff distance, a change in the number of pseudopods, and/or a shape of at least one adhered cell. In some cases, the method further comprises using the non-uniformity parameter, Hausdorff distance, change in the number of pseudopods, and/or shape of the adhered cell to identify the adhered cell as a tumor cell or a non-tumor cell.
