Abstract
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.
