Biosensor systems and methods for determining the presence of biomolecules

摘要

Systems and method for determining the presence of biomolecule are disclosed. Briefly described, a representative biosensor system 100 includes a target complex 150 disposed on a conductive substrate 105. The target complex 150 includes a target biomolecule 115 and a target nanoparticle 125. The target nanoparticle 125 is disposed on the target biomolecule 115. In addition, the biosensor includes an image nanoparticle 135 disposed on the target nanoparticle 125. The image nanoparticle 135 is electrochemically deposited on the target nanoparticle 125. The biosensor system also includes a detector capable of determining the presence of the target biomolecule 115 by detecting the image nanoparticle 135. <IMAGE>
