Cancer Nanotechnology
Nanotechnology offers exceptional specificity, sensitivity, and the ability to perform multiplexed measurements, making it a promising tool for the detection of extracellular cancer cells, cancer biomarkers, and in vivo imaging. While it has not yet been widely adopted for clinical cancer diagnosis, nanotechnology is already utilized in various diagnostic platforms—for example, gold nanoparticles are used in commercial home pregnancy tests. In cancer diagnostics, nanoparticles are being explored for their ability to capture key cancer biomarkers, including circulating tumor DNA (ctDNA), circulating tumor cells (CTCs), exosomes, and cancer-associated proteins.
