Identity profiling of cell surface markers by multiplex gold nanorod probes

Research output: Contribution to journalArticlepeer-review


Gold nanorod molecular probes (GNrMPs) were designed and fabricated for multiplex identification of cell surface markers in HBECs. Cells were probed directly using dark field microscopy integrated with a spectral imager for simultaneous detection of up to three surface markers. The immunophenotype composition of these cell lines indicative of their metastasis potential was assessed using the GNrMPs. The technique has the potential to become an important tool for diagnosis and prognosis of breast and other cancers.
