Patent number: 10926258Abstract: Microfluidic probe head for processing a sequence of separate liquid volumes separated by spacers. The microfluidic probe head includes: an inlet, an outlet, a first fluid channel and a second fluid channel and a fluid bypass connecting the first fluid channel and the second fluid channel. The first fluid channel delivers the sequence of separate liquid volumes from the inlet toward a deposition area, the fluid bypass allows the spacers to be removed from the first fluid channel obtaining a free sequence of separate liquid volumes without spacers, the first fluid channel delivers the free sequence of separate liquid volumes to the deposition area, and the second fluid channel delivers the removed spacers from the fluid bypass to the outlet. The present invention also provides a microfluidic probe and method for processing a sequence of separate liquid volumes.Type: GrantFiled: March 30, 2020Date of Patent: February 23, 2021Assignee: International Business Machines CorporationInventors: Julien Autebert, Emmanuel Delamarche, Govind Kaigala, Xander Frank Van Kooten

Patent number: 10357770Abstract: A microfluidic probe is disclosed. The microfluidic probe includes a probe head, a liquid spacer supply and a spacer modulation unit. The probe head may include a processing liquid channel in fluid communication with a processing liquid aperture provided on a face of the probe head. The probe head is configured to transport, circulate, recirculate, or move some processing liquid in (or via) the processing liquid channel toward and/or from the processing liquid aperture. The spacer supply is fluidly connected, via a spacer insertion junction, to the processing liquid channel. The spacer supply is configured for inserting liquid spacers into the processing liquid channel, via the spacer insertion junction. Liquid volumes can be obtained, which are separated by inserted liquid spacers. The spacer modulation unit is configured to control the spacer supply, to modulate the insertion of spacers via the spacer supply. Related devices and methods of operation are disclosed.Type: GrantFiled: October 9, 2015Date of Patent: July 23, 2019Assignee: International Business Machines CorporationInventors: Julien Autebert, Julien Cors, Emmanuel Delamarche, Govind Kaigala, Xander Frank Van Kooten
