Abstract Diamond enables the construction of various (bio)sensors, including those with quantum‐based detection. However, bare diamond interfaces are susceptible to unspecific adhesion proteins and other macromolecules from biological media or complex samples. This impairs selectivity in biosensing, leads low signal‐to‐noise ratio fluorescence‐based applications, introduces need for blocking steps incubation protocols. Here, a stable, protein‐repellent, clickable reactive polymer coating is...
