Abstract

Abstract: Conjugation between various small fluorophores and specific ligands has become one of the main strategies for bioimaging in disease diagnosis, medicinal chemistry, immunology, and fluorescence-guided surgery, etc. Herein, we present our review of recent studies relating to molecular fluorescent imaging techniques for various cancers in cell-based and animal-based models. Various organic fluorophores, especially near-infrared (NIR) probes, have been employed with specific ligands. Types of ligands used were small molecules, peptides, antibodies, and aptamers; each has specific affinities for cellular receptor proteins, cancer-specific antigens, enzymes, and nucleic acids. This review can aid in the selection of cancer-specific ligands and fluorophores, and may inspire the further development of new conjugation strategies in various cellular and animal models.
