Patent number: 12115532Abstract: A cartridge, in particular a disposable cartridge, for use in an electrowetting sample processing system. The cartridge contains an internal gap with at least one hydrophobic surface for enabling an electrowetting induced movement of a microfluidic droplet that has magnetic beads and further has a bead accumulation zone, into which the microfluidic droplet is transferable by electrowetting force and the magnetic beads are exposable to a magnetic force of a bead manipulation magnet. The internal gap has a bead extraction opening adjacent to the bead accumulation zone. The bead extraction opening provides a passage from the gap to an exterior space of the cartridge and is configured to removably receive the bead manipulation magnet for enabling an extraction of the magnetic beads from the microfluidic droplet by a removal of the bead manipulation magnet.Type: GrantFiled: April 25, 2023Date of Patent: October 15, 2024Assignee: TECAN TRADING AGInventors: Patrick Kinney, Sujata Iyer, Tin Ngo, Jennifer Ji, Marta Matvienko, Tiffany Ding (Lay)

Publication number: 20240118239Abstract: A cartridge for use in an electrowetting sample processing system, the cartridge having one or more inlet ports for introducing an input liquid into an internal gap of the cartridge, which has at least one hydrophobic surface for enabling an electrowetting induced movement of multiple microfluidic droplets separated from the input liquid. The cartridge further has at least one outlet port that is operably connected to the inlet port for providing a liquid flow through the cartridge, if a liquid driving force, in particular an electrowetting force or a pressure force, is applied to at least a part of the input liquid.Type: ApplicationFiled: December 15, 2023Publication date: April 11, 2024Inventors: Patrick Kinney, Sujata Iyer, Daniel Hoffmeyer, Manjeet Dhindsa, Tin Ngo, Tiffany Ding (Lay), Torleif Ove Björnson

Patent number: 11951482Abstract: A cartridge, in particular a disposable cartridge, for use in an electrowetting sample processing system. The cartridge has a liquid input port for introducing an input liquid into an internal gap of the cartridge, the input liquid providing for at least one droplet, directly or via a liquid separation process within the internal gap, and the internal gap having at least one hydrophobic surface, at least one processing zone for processing samples located in the processing zone, and a delivery zone for delivering the at least one droplet from the liquid input port to the at least one processing zone. The delivery zone is configured to provide a repeating pattern of interacting electrowetting force for simultaneously transporting the at least one droplet within the delivery zone.Type: GrantFiled: December 22, 2021Date of Patent: April 9, 2024Assignee: TECAN TRADING AGInventors: Patrick Kinney, Tiffany Ding (Lay), Manjeet Dhindsa, Daniel Tran, Jennifer Ji, Sujata Iyer, Tin Ngo
