Abstract

Biomaterial has a wide variety of usages in medicine and chemistry. The biomaterials used in medicine and chemistry are often polymers. Polymers used as biomaterial must be compatible to the environment and they must not be poisonous and in case they are broken down they must not provide poisonous products in biological environment. The biomaterial used for each case has certain and specific chemical and physical characteristics. The proteins are absorbed as form of the biomaterial. This protein layer provides suitable environment to absorb later proteins, lipids and other materials. We have offered a new and effective method to increase the bioadaptability of biomaterial. We studied active chemical groups in order to cover the cases of covalent link production. The protein absorption steps can occur if Gibbs energy is decreased.

Key words: Biomaterial, compatibility, contact lenses.
