Facilitating controlled particle deposition from droplet dispensers

A method of facilitating controlled particle deposition from a droplet dispenser includes: receiving at least one pre-dispensing image of a dispensing portion of the droplet dispenser, the dispensing portion including a fluid to be dispensed as a subject droplet to a subject target area; receiving at least one post-dispensing image of a dispensing portion of the droplet dispenser after dispensing the target droplet; comparing the at least one pre-dispensing image and the at least one post-dispensing image to determine a subject droplet particle count representing a count of particles included in the subject droplet; and generating a signal for associating a representation of the subject droplet particle count with the subject target region. Other methods, apparatus, systems, and non-transitory computer readable media are also disclosed. 一种促进来自液滴分配器的受控颗粒沉积的方法包括：接收液滴分配器的分配部分的至少一个分配前图像，分配部分包括将以对象液滴分配至对象目标区域的流体；在分配对象液滴之后，接收液滴分配器的分配部分的至少一个分配后图像；比较至少一个分配前图像和至少一个分配后图像，以确定表示包括于对象液滴中的颗粒的计数的对象液滴颗粒计数；以及产生用于将对象液滴颗粒计数的表示与
