The invention provides a method for producing a substrate for supporting cells, including a humidification step of humidifying the periphery of a non-fluorine resin based substrate, and a UV irradiation step of irradiating the substrate with UV in an oxygen and/or ozone containing atmosphere during and/or after the humidification step. The invention also provides a substrate for supporting cells, which is a non-fluorine resin based substrate. The substrate has a cell supporting surface for supporting cells, containing a component capable of generating CHOmolecules by beam irradiation of a time-of-flight secondary ion mass spectrometer, such that cells are supported on the cell-supporting surface.

Substrate for supporting cells and method for producing same

The present invention relates to provide a drawn optical transmission medium having excellent heat resistance and a continuous refractive index distribution in a good productivity at a low cost, and the disadvantages in a conventional synthetic resin optical transmission medium can be eliminated, which method is characterized by a step of crosslinking a polymer having a continuous refractive index gradient distributed from the peripheral portion to the central portion in its cross section and having a crosslinkable functional groups, after the step of heating and drawing.

Synthetic resin optical transmission medium and its preparation method

A method for preparing a polymer rod for optical transmission media. The process involves copolymerization of monomers having different boiling points by removal of monomer vapor during polymerization. The process results in a transition in refractive index along the radial direction of the polymer rod.
