The red-shift fluorescent is often observed from the biomolecules covalently coupled with the core/shell quantum dots, while blue shift fluorescent from the electrostatic adsorption coupling structures. These fluorescent effect characteristics are analyzed on the basis of the quantum theory of condensed matter, and are demonstrated to be mainly related with the elementary excitation.
The microscopic mechanism of laser-biomolecule interaction is analyzed by quantum theory, including the interactions
of laser with the chain of the biomolecular in the damping case and undamping case. The results show that the
interaction of laser with DNA may result in the system getting into a chaotic state of biomolecules due to damping effect
and changing the original molecular conformational, which will contribute to the improvement of laser medical.
The interaction between laser and C-SQDB bio-molecule which is related with the fluorescence effect, thermal effects
and eliectrical effect from the coupling structure of quantum dots bonded with bio-molecules and of have been wildly researched for the potential application in life science. .As one of the most problems, the electrical effects are analyzed by employing quantum theory in this paper and The research will be conducive to the practical application of C-S QDBS
in medical science.
