Abstract

Nanomaterials with the ability of sequestering target molecules hold great potential for a variety of applications. To ensure the stable sequestration, most of these nanomaterials have been traditionally designed with a clear boundary or compact structures and behave as closed systems. While this feature is beneficial to applications such as drug delivery, it may pose a challenge to applications where fast molecular transport from the environment to nanomaterials is critical. Thus, this study was aimed at exploring a nanomaterial with affinity DNA polymers and nanoparticles as an open system with function similar to jellyfish tentacles in sequestering target molecules from surroundings. The results show that this nanomaterial can effectively and rapidly sequester both small molecule drugs and large molecule biologics and resultantly mitigate their biological effects. Thus, this nanomaterial holds potential as a universal nanoscale antidote for drug removal and detoxification. While this nanomaterial was evaluated by using drug removal and detoxification as a model, the synthesis of periodically oriented affinity polymers on a nanoparticle with the capability of sequestering target molecules may be tuned for broad applications such as separation, sensing, imaging and drug delivery.
