METHODS AND COMPOSITIONS IN PARTICLE-BASED DETECTION OF TARGET MOLECULES USING LINKING MOLECULES

摘要

Methods and compositions which can be used to increase the strength and/or probability of forming a binding complex comprising a target molecule and a substrate are disclosed. In one aspect, linking molecules are disclosed which can be used to increase the number of intra-complex binding interactions. Covalent bonds can be introduced to further increase the strength of these binding interactions. Inter-complex cross-linking can be utilized in connection with these methods to further strengthen and stabilize the disclosed binding complexes.
