Cryopreservation of a cell-based biosensor chip modified with elastic polymer fibers enabling ready-to-use on-site applications.

含活细胞的细胞基生物传感器芯片难以长期保存，尤其是贴壁哺乳动物细胞在传感器表面易受冷冻损伤。本文提出一种传感器上冷冻保存（on-sensor cryopreservation, OSC）策略，将贴壁细胞在光寻址电位传感器（light-addressable potentiometric sensor, LAPS）表面于−80 °C冷...
