A method of making a phosphono-phosphate compound is disclosed. The method involves a first step of mixing a first component comprising a phosphonic acid, a phosphonate or mixtures thereof, with a second component comprising a source of phosphoric acid or phosphate. The mixture has a molar phosphorous ratio of the first component to the second component of from 1:1 to 1:10. The second step involves either physically or chemically dehydrating the mixture to produce a phosphono-phosphate compound.

Zwitterionic polymers or biocompatible polymers with improved properties for cell encapsulation, coating of devices, or a combination thereof are described. The biocompatible polymer contains a zwitterionic monomer, a monomer with a reactive side chain, and optionally another hydrophobic monomer or a neutral hydrophilic monomer. The zwitterionic polymers are cross-linked with a cross-linker via covalent bond to form a zwitterionic hydrogel in the presence of cells. Also provided, are methods of making and using the zwitterionic polymers.
