Abstract
There is provided a new material that can form a finer pattern and can be applied to adsorption/adhesion control of various cell species, proteins, viruses, and the like without the limitation of the light source. A light-degradable material comprising: a moiety that is capable of bonding to a surface of a substrate through a siloxane bond; and a structural unit of Formula (2-a) and/or Formula (2-b):(where R2 to R4 are saturated linear alkyl groups; X is a hydrogen atom or an alkyl group; Z is a carbanion or a sulfo anion; Q is an ester bond group, a phosphodiester bond group, an amido bond group, an alkylene group, or an phenylene group or a combination of these divalent groups; m1 is an integer of 1 to 200, and n is an integer of 1 to 10).
