A medical member includes a base material that is permeable to light; and a polymer layer having a phosphorylcholine group and located at least at a part of an inner surface of the base material. The part of the inner surface includes a first area irradiated with light of an intensity capable of forming the polymer layer when irradiated with light of a predetermined intensity from an outer surface side of the base material. Another medical member includes a base material that is permeable to light; and a polymer layer having a phosphorylcholine group and located at least at a part of an inner surface of the base material. The inner surface of the base material is irradiated with light of a light intensity of 3 mW/cm.sup.2 or less when light of a light intensity of 15 mW/cm.sup.2 or less enters from an outer surface side of the base material.

Some embodiments of the present disclosure relate to polymerizable compounds that comprise biocidal activity and/or the potential for increased biocidal activity and that comprise at least one hydrophobic portion and at least one hydrophilic portion. Together the hydrophobic portion and the hydrophilic portion of the compounds may provide the polymerizable compounds with one or more surfactant-like properties. The polymerizable compounds can be incorporated into polymer coating formulations. The polymer coating formulations can be used to coat one or more surfaces of a substrate. The coating formulation can provide biocidal activity and/or the potential for increased biocidal activity to the coated substrate-surface.
