  We demonstrate that a controlled and homogenous distribution of isolated
nano-particles can be achieved in deposition by employing a single stage
deposition technique, utilizing a commercial ultrasonic humidifier to produce
micrometer scale droplets from a suspension containing nano particles.
Nano-diamonds were uniformly distributed on a Si substrate using this method. P
article density was controlled by varying the deposition time. The spatial
distribution of the nano particles is shown to be uniform and with no
aggregation. We propose that this method can be utilized in developing mass
production processes of nano devices where a homogenous sub monolayer of
nano-particles is required.
