Abstract: A nanowires/microscale pyramids (NWs/MPs) substrate complex structure is formed with a plurality of pyramids. Each triangular surface of the pyramid is formed with nanowires to increase the contact area. In one application, anti-epithelial-cell adhesion-molecule (anti-EpCAM) antibodies are modified on the nanowires. The anti-EpCAM antibodies serve to capture circulating tumor cells (CTCs) in blood for determining whether the cancer cells have metastasized to other organs. In another application, the nanowires are modified with silver nanoparticles (AgNPs) which can be combined with other functional groups for testing. The AgNPs on the NWs/MPs substrate causes the NWs/MPs substrate to become a substrate with surface enhanced Raman scattering (SERS). The AgNPs are bound with Epstein-Barr virus (EBV) probe DNA which can be hybridized with EBV target DNAs so as to determine the concentration of the EBV target DNAs in blood. The methods for fabricating the substrate and its applications are also provided.

Abstract: The preset invention relates to a process for discovering potential treatment strategy for a given disease, providing a niche for PPI network construction, target prioritization, and potential drug identification for a given disease, particular a cancer, based on the interaction between prioritized NPC targets (e.g. cliques and bottleneck genes) and drugs.
