    摘要： Methods of preparing organic nanoparticles are provided. Such methods can include generating a mixture of an organic material, a first liquid, and a second liquid, wherein the organic material is more soluble in the second liquid than in the first liquid. The methods can also include adding a third liquid to the mixture which causes the mixture to form an emulsion. Such an emulsion can have a continuous phase including the first liquid and a discontinuous phase including the organic material and the second liquid. The organic material can be precipitated to form organic nanoparticles and the second liquid can diffuse into the continuous phase.

    摘要： A printing device is provided, which is configured to print a printing fluid onto a printing medium. The printing device includes a printing fluid reservoir configured to hold a volume of the printing fluid, a print head assembly configured to transfer the printing fluid to the printing medium, a conduit fluidically connecting the printing fluid reservoir to the print head assembly, and a printing fluid detector associated with the conduit. The printing fluid detector includes a first electrode and a second electrode coupled with the conduit and configured to be in contact with printing fluid in the conduit, a power supply configured to apply an alternating supply signal to the first electrode, and detector circuitry configured to detect a measured impedance value related to the presence of printing fluid within the conduit by comparing the alternating supply signal with a detected signal that has been modified from the applied signal by an impedance characteristic of the printing fluid.
