Patent number: 11278888Abstract: An example device includes a first microfluidic channel in communication with a fluid reservoir to receive cell-containing fluid from the fluid reservoir. The device further includes a second microfluidic channel in communication with the fluid reservoir to receive cell-containing fluid from the fluid reservoir. The device further includes a first sensor disposed at the first microfluidic channel, a second sensor disposed at the second microfluidic channel, a first dispense nozzle disposed at an end of the first microfluidic channel, and a second dispense nozzle disposed at an end of the second microfluidic channel. The first microfluidic channel is shaped to convey cells of a first size range, and the second microfluidic channel is shaped to convey cells of a second size range that is different from the first size range.Type: GrantFiled: April 3, 2018Date of Patent: March 22, 2022Assignee: Hewlett-Packard Development Company, L.P.Inventors: Jeffrey A.
