Abstract:
1. A microtray for handling biosubstances comprising: a fluid holding structure including an array of wells with each well configured to contain at least one biosubstance; a fluid ejection structure arranged vertically below, and connected to, the fluid holding structure to define a single unit, the fluid ejection structure including an array of drop-on-demand fluid ejection devices with each fluid ejection device being in fluid communication with at least one of the respective wells and including at least one nozzle, wherein the fluid ejection structure includes circuitry configured to independently activate each respective fluid ejection device and configured to cause, independent of a target media, dispensing of the at least one biosubstance from the at least one nozzle of a respective one of the fluid ejection devices onto the target media; an electrically conductive input/output contact element configured to communicate with an external controller; and a fluid processor interposed between, and in fluid communication with, the fluid holding structure and the fluid ejection structure, and configured to route the at least one biosubstance from the respective wells to the respective fluid ejection devices, wherein the fluid processor is electrically activated via the input/output contact element and the fluid processor includes at least one of:
