We present electrical measurements of single Au and CdSe nanocrystals. The devices are fabricated using a hybrid scheme which combines electron beam lithography and wet chemistry to bind nanocrystals in tunneling contact between two closely spaced metallic leads. The current{endash}voltage characteristics of these devices exhibit a Coulomb staircase with a charging energy of {approximately}50 meV. This technique is readily adapted to the study of a host of nanocrystals made by solution chemistry. {copyright} {ital 1996 American Institute of Physics.}
