Abstract

Carbohydrate recognitions are crucial events in many biological processes including cellular adhesion, cell signaling, cell-cell communication, immune response, cancer development and metastasis. Understanding the specific interaction between carbohydrates and carbohydrate-binding proteins (CBPs) could lead to clarifying the functions of both molecules and their underlying molecular mechanism and discovering therapeutic and diagnostic mechanism as well, but it is a challenging task. This work demonstrates aqueous dispersions of single-wall carbon nanotubes (SWCNTs) stabilized by multivalent, galactose-containing glycopolymers that closely mimic the natural glycan structures and functions. In addition, the specific binding behavior of glycopolymer-functionalized SWCNTs with CBPs and its role as an effective measurement tool for profiling carbohydrate-protein recognitions will be discussed.
