      abstract     = {The detection of faint magnetic fields from single-electron
                      and nuclear spinsat the atomic scale is a long-standing
                      challenge in physics. While currentmobile quantum sensors
                      achieve single-electron spin sensitivity, atomicspatial
                      resolution remains elusive for existing techniques. Here we
                      fabricate asingle-molecule quantum sensor at the apex of the
                      metallic tip of a scanningtunnelling microscope by attaching
                      Fe atoms and a PTCDA
                      (3,4,9,10-perylenetetracarboxylic-dianhydride) molecule to
                      the tip apex. We address themolecular spin by electron spin
                      resonance and achieve ~100 neV resolutionin energy. In a
                      proof-of-principle experiment, we measure the magnetic
                      andelectric dipole fields emanating from a single Fe atom
                      and an Ag dimer on anAg(111) surface with sub-angstrom
                      spatial resolution. Our method enablesatomic-scale quantum
                      sensing experiments of electric and magnetic fields
                      onconducting surfaces and may find applications in the
                      sensing of spin-labelledbiomolecules and of spin textures in
                      quantum materials.},
