Patent number: 12485419Abstract: A heterogeneous population of cells are separated and collected according to a method. The heterogeneous population of cells in a paramagnetic medium are placed in a fluidic channel in which the fluidic channel comprises two or more outlets. The heterogeneous population of cells in the fluidic channel are separated based on differences in magnetic susceptibility and density of the heterogeneous population of cells. Fluid comprising the separated cells is withdrawn from the two or more outlets using variable flow rates by fluidic pumps at respective ones of the two or more outlets simultaneously to fractionalize the fluid comprising the separated cells across the two or more outlets by manipulation of the variable flow rates relative to one another.Type: GrantFiled: April 20, 2022Date of Patent: December 2, 2025Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Murat Baday, Naside Gozde Durmus, Semih Calamak, Utkan Demirci, Ronald W. Davis, Lars Steinmetz, Jaeyoung Yang, Thiruppathiraja Chinnasamy, Alessandro Tocchio

Publication number: 20240361343Abstract: Magnetic cell levitation and cell monitoring systems and methods are disclosed. A method for separating a heterogeneous population of cells is performed by placing a microcapillary channel containing the heterogeneous population of cells in a magnetically-responsive medium in the disclosed levitation system and separating the cells by balancing magnetic and corrected gravitational forces on the individual cells. A levitation system is also disclosed, having a microscope on which the microcapillary channel is placed and a set of two magnets between which the microcapillary channel is placed. Additionally, a method for monitoring cellular processes in real-time using the levitation system is disclosed.Type: ApplicationFiled: July 12, 2024Publication date: October 31, 2024Inventors: Utkan Demirci, Ionita Ghiran, Savas Tasoglu, Ronald W. Davis, Lars Steinmetz, Naside Gozde Durmus, Huseyin Cumhur Tekin

Publication number: 20230340608Abstract: The present invention pertains to a new method for the prognosis, diagnosis, stratification and/or monitoring of a therapy of a disorder in a subject. The method is based on the determination of the level of at least one first biomarker indicative and/or selective for the status and/or activity of the pathway regulating N6-methyladenosine (m6A) mRNA modification, and the determination of the level, mutation status, and/or activity of at least one second biomarker indicative and/or selective for the status and/or activity of the pathway regulating 5-methoxycarbonylmethyl-2-thiouridine (mcm5s2U)-tRNA modification as combined biomarkers. The new biomarkers of the invention allow diagnosing and even stratifying of a disorder in a patient, estimating a patient's prognosis, and monitoring therapy success of patients, in particular of cancer patients, such as breast cancer patients. Further provided are kits for the prognosis, diagnosis, and/or monitoring of a disease, condition or disorder in a subject.Type: ApplicationFiled: July 16, 2021Publication date: October 26, 2023Inventors: Bastian LINDER, Lars STEINMETZ, Sebastian LEIDEL

Patent number: 11338290Abstract: Systems and methods for levitating populations of moieties, cells, or other such units using one or more magnets in a microfluidic environment are provided. These systems and methods may be used to, for example, separate or sort heterogeneous populations of the units from one another, to assembly a multi-unit assembly during the levitating of the units, and to evaluate samples at the point of care in real-time. These systems and methods may also utilize a frame that enables an imaging device, such as a smartphone, to capture the units in real time as they are manipulated in the system.Type: GrantFiled: September 30, 2016Date of Patent: May 24, 2022Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Murat Baday, Naside Gozde Durmus, Semih Calamak, Utkan Demirci, Ronald W.
