Durable polyurea copolymer coatings can be applied to surfaces that come in contact with fluids, such as biological fluids, thereby passivating the surface. Polyurea copolymer coating compositions comprise a reaction product of (a) a diamine composition that includes a polyethylene glycol diamine, and optionally, a dipiperidyl alkane; and (b) a diisocyanate. Solutions containing polyurea copolymers, coated surfaces and methods are also described.

Inventive concepts relate generally to the field of cell culture, and more particularly to formation of three-dimensional aggregate(s) of eukaryotic cells. Cell culture vessels including a conical device having an inner surface being hydrophobic; and a frustum defining an open viewing aperture and a narrow end of the conical device are described. Ceil culture vessel arrays, assemblies and kits are described, as well as methods of making and using the devices.
