Summary
Rapid detection of biological molecules helps protect public health, monitor the environment, and enable timely medical decisions. Many biosensors operate slowly because target molecules must diffuse a long distance to reach the sensing surface. The delay increases testing costs and reduces sensitivity. This project will build a nanostructure that guides target molecules toward a sensing surface. The structure will have flexible DNA “tentacles” that attract target molecules and concentrate them near the surface. The result will be faster detection and improved sensitivity. The new technology w
