摘要：

An optically transparent biomaterial is produced by encapsulating a light-transducing protein, phycoerythrin, in a sol-gel matrix. Absorption and fluorescence measurements indicate that the protein not only retains its native optical properties in the sol-gel matrix but also shows an enhanced stability toward photodegradation. Two-photon induced fluorescence is observed from phycoerythrin in both solution and sol-gel matrices. The potential application of this biomaterial in biosensors, three-dimensional biomolecular imaging, and three-dimensional optical storage is discussed.
