| Research Abstract |
A bacterium Pseudomonas aeuginosa RB-R was isolated for synthesizing cadmium selenide(CdSe) from slenite and cadmium ion. TEM-EDX observation indicated that 10-20 nm CdSe particles were formed inside and surface of the bacterial cells. The extracted particles from the bacterial culture showed 200 nm in diameter. Production of nano-scale CdSe particles will be possible if polar organic chemicals are added to the synthetic process for preventing coagulation.
