A new method of encapsulating tissues was developed using photoactivated polyethylene glycol (PEG). Bulk phase and interfacial polymerization techniques were used to encapsulate the islets of Langerhans. The effects of polymerization variables on encapsulation were studied. Among the variables, the concentrations of eosin Y (EY), PEG, and triethanolamine (TEA) were found to be most critical. Data on the percentage of islets showing fibroblast growth indicated the uniformity of the PEG coating and its ability to prevent cellular outgrowth. In addition, PEG was able to prevent cell death via complement for periods up to 3 hours.
