Although several imaging modalities are widely used for tumor imaging, none are tumor type-specific. Different types of cancer exhibit differential therapeutic responses, thus necessitating development of an imaging modality able to detect various tumor types with high specificity. To illustrate this point, CD30-specific oligonucleotide aptamer in vivo(More)
The current antibody-mediated numeration assays of circulating tumor cells (CTCs) require multiple steps and are time-consuming. To overcome these technical limitations, a cancer cell-activatable aptamer-reporter was formulated by conjugating a biomarker-specific aptamer sequence with paired fluorochrome-quencher molecules. In contrast to the antibody(More)
A novel cell-permeable compound, CypH-1, that is non-fluorescent at neutral pH, but fluoresces under mildly acidic conditions with a near infrared maximum emission wavelength was designed for the detection of tumors in the clinical setting. The potential of CypH-1 in ovarian cancer imaging was demonstrated using a murine model. The intraperitoneally(More)
