Abstract :
Micromachining techniques have been employed to manufacture microparticles bearing an engraved dot-type signature for biomolecular encoding. In addition, the code introduced on the particle face is a straightforward visible feature that is easily recognizable with the use of optical microscopy on the grounds of the CdSe Quantum dots (QDs) as fluorescent probes. In this paper, An integrated CMOS circuit for detection of very low-level bioluminescence is presented.
