| 20090270275 | METHOD AND APPARATUS FOR SCANNING BIO CHIPS USING LIGHT AMPLICATION BY METAL NANO-PARTICLES - The present invention utilizes a principle in which, in a state in which metal nano-particles are attached to target probes and used as markers, and the metal nano-particles have a proper density according to a bio reaction between the target probes and fixed probes, when the metal nano-particles are irradiated with a laser beam having a proper intensity from the optical pick-up head, a higher optical energy is delivered to the phase change layer by an optical amplification effect caused by the metal nano-particles, thereby better inducing an amorphous-to-crystalline phase change. | 10-29-2009 |
