Generation of High-Affinity Aptamer-MIP Hybrid Nanoparticles.
Abstract
Aptamers and molecularly imprinted polymers (MIPs) are two leading technologies used for the development of protein biomimetics. By combining the two technologies, a new hybrid class of materials can be created, which utilizes the interesting characteristics of both recognition materials, while negating several of their drawbacks. This chapter describes the protocol for the synthesis of aptamer-MIP hybrid nanoparticles. These materials exhibit exceptional affinity (into the nM range) and selectivity for their target template. They can be developed for a wide range of targets, while exhibiting excellent robustness, solubility, and flexibility in use. These are a new class of recognition materials with the potential for use as drug delivery vectors, as well as use within sensing and recognition assays.
