Superconducting circuits have shown their ability to enhance the detection of electronic spins down to the few spins level. However, these demonstrations have so far been done using well-known model spin systems and in restrictive conditions: very narrow spin and detector linewidths, and in absence of microwave losses. In this poster, I will describe our progress towards adapting this technique to a broader range of samples, encompassing possible chemical or biological applications.
