Abstract
Aptamers, which are selected in vitro by a technology known as the systematic evolution of ligands by exponential enrichment (SELEX), represent a crucial recognition element in molecular sensing. With advantages such as good biocompatibility, facile functionalization, and special optical and physical properties, various nanomaterials can protect aptamers from enzymatic degradation and nonspecific binding in living systems and thus provide a preeminent platform for biochemical applications. Coupling aptamers with various nanomaterials offers many opportunities for developing highly sensitive and selective sensing systems. Here, we focus on the recent applications of aptamer-assembled nanomaterials in fluorescent sensing and imaging. Different types of nanomaterials are examined along with their advantages and disadvantages. Finally, we look toward the future of aptamer-assembled nanomaterials.
