ABSTRACT
Since diseased cells exist in exceedingly low concentration at the early stage of cancer, highly sensitive imaging and detection methods are required. By improving the methods for capturing and visualizing cancer cells, clinicians can diagnose metastatic relapse, stratify patients for therapeutic purposes, monitor response to drugs and therapies, and track tumor progression. Therefore, using advanced biotechnological and analytical methods combined with cell-SELEX (systematic evolution of ligands by exponential enrichment)-based aptamers, we improved the capture and visualization of diseased cells in a manner that is inexpensive, simple, sensitive, and fast. This multiplexed cancer detection platform therefore improves our control over a range of clinical exigencies, including cancer diagnosis, therapeutic modalities, and drug delivery systems.
