Abstrakt

We present a proof-of-principle study of superconducting single photon detectors (SSPD) for

the detection of individual neutral molecules/nanoparticles at low energies. The new detector is

applied to characterize a laser desorption source for biomolecules and allows retrieval of the

arrival time distribution of a pulsed molecular beam containing the amino acid tryptophan, the

polypeptide gramicidin as well as insulin, myoglobin and hemoglobin. We discuss the

experimental evidence that the detector is actually sensitive to isolated neutral particles.
