“…The literature shows that the deposition of different reflecting materials and probes anchoring on the surface of CDs for analytical applications is a poorly studied area, except for a few research works which delved into the surface plasmon resonance (SPR) phenomenon on CDs. , Other works report interferometric biosensors by the deposition of radial spokes made of gold ridges on a high-reflectance substrate, e.g., a silicon wafer. , Recordable gold CDs have been utilized to prepare alkanethiolate self-assembled monolayers, − electrodes, and microchips for electrochemistry studies, , or to produce material microstructures . All the above-mentioned approaches damage the disc structure, track, and surface, which are no longer readable by a standard drive …”
