  • MICROFLUIDIC DEVICE AND METHOD FOR FORMING A CELL ASSEMBLY, AND METHOD FOR SELECTIVELY TREATING A CELL WITHIN SUCH A CELL ASSEMBLY
    Publication number: 20260208191
    Abstract: The invention relates to a microfluidic device (1) for forming a cell assembly comprising at least one first cell (C1) and one second cell (C2) and for individually treating a selected cell of said cell assembly, comprising: —a microfluidic channel (10); —at least one main inlet (11) for a fluid containing first cells, respectively second cells, arranged in a first portion (101) of the microfluidic channel; —an outlet (12) arranged in a second portion (102) of the microfluidic channel for controlling a fluid flow rate in the microfluidic channel; —at least one first auxiliary inlet (131) for a first auxiliary fluid arranged in the first portion (101) of the microfluidic channel upstream or downstream of the main inlet (11); —at least one cell trap (14) arranged in the microfluidic channel between the first portion and the second portion, wherein each cell trap (14) comprises at least one first trapping portion (141) and one second trapping portion (142), each first and second trapping portion being sized to r

  • DEVICE AND METHOD FOR TRAPPING CELL PAIRS, AND METHOD FOR ANALYSING CELL PAIRS IN REAL TIME
    Publication number: 20250345794
    Abstract: The invention relates to a device for trapping at least one cell pair in a solution containing at least one first cell (C1) of a first type and at least one second cell (C2) of a second type, comprising: —a microfluidic channel (3) adapted for a unidirectional flow (F) of the solution; —a first trap (1) comprising a pair of first fingers (10a, 10b) arranged in the microfluidic channel (3), at least one of said first fingers (10a, 10b) being coupled to a respective first actuator (11a, 11b), said first actuator being configured to adjust the first trap (1) along a direction transversal to the flow (F) between an open position allowing passage of the first cell between the first fingers (10a, 10b) and a closed position adapted to a size of the first cell to allow trapping the first cell between the first fingers (10a, 10b); 15—a second trap (2) comprising a pair of second fingers (20a, 20b) arranged in the microfluidic channel (3), at least one of said second fingers (20a, 20b) being coupled to a respective sec
