Abstract
Provided are a biochip platform for biochemically analyzing a sample such as DNA or protein, including a dielectric particle layer, and an optical assay apparatus including the same. The biochip platform includes the dielectric particle layer uniformly formed on a substrate. The particle uniformity of the dielectric particle layer enables good wavelength separation of fluorescence signal, and the large surface area of the dielectric particle layer guarantees better amplifications efficiency of fluorescence signal. Furthermore, the biochip platform shows good economical efficiency due to easy fabrication process, and is particularly useful in an optical assay apparatus for analyzing a biochemical sample due to good assay efficiency.
