Long-acting surface modification carrier for promoting cell adherence

The invention provides a long-acting surface modification carrier for promoting cell adherence, and relates to the technical field of cell culture.The long-acting surface modification carrier is made of PET and is of a multi-layer fiber roll film of a film net support three-dimensional structure which is arranged in a criss-cross mode, the surface of the PET film is subjected to hydrophilic treatment through a plasma modification method, and the surface of the PET film is subjected to hydrophilic treatment; and carrying out secondary hydrophilic modification treatment on the surface through a grafting process to form a long-acting surface modification carrier. According to the invention, as the hydrophilic performance of the PET film subjected to long-acting modification treatment by the plasma is greatly improved, the attachment rate of cells is obviously improved, and the cell inoculation suspension is utilized at the maximum efficiency, so that unnecessary waste of biological materials is avoided, the inoc
