APTAMER-BASED COLORIMETRIC SENSOR SYSTEMS

摘要

The present invention provides an aptamer-based colorimetric sensor system for determining the presence and optionally the concentration of an analyte in a sample. Methods of utilizing the sensor system and kits that include the sensor also are provided. The sensor utilizes a linker and oligonucleotide functional ized particles to form an aggregate, which disaggregates in response to the analyte.
