  • Patent number: 7670831
    Abstract: Conductive carbon nanotubes (CNTs) obtained by dotting carboxylated CNTs with metal nanocrystals by chemical functional groups, are described, as well as a method for fabricating a pattern or film of the conductive CNTs which involves repeatedly depositing conductive CNTs on a substrate to achieve high surface density. A biosensor is described, in which bioreceptors that bind to target biomolecules are selectively attached to conductive CNTs or a conductive CNT pattern or film. By use of the conductive biosensor, various target biomaterials that bind or react with the bioreceptors can be precisely measured directly or by electrochemical signals at large amounts in one step. Additionally, the biosensor can be used for an electrical detection method capable of providing precise measurement results even with a small amount of source material.

  • Publication number: 20100035362
    Abstract: The present invention relates to a bio-silica chip comprising a silica-binding protein and a fabrication method thereof, and more particularly to a bio-silica chip in which a fusion protein of a silica-binding protein and a probe protein is immobilized on a chip comprising a silica layer, a fabrication method thereof and a method of using the bio-silica chip to detect interactions with biomaterials. The bio-silica chip will be very useful in biosensors, etc., because the bio-silica chip is advantageous in that it does not cause non-specific protein binding in the detection of protein-DNA, protein-ligand, protein-antibody, protein-peptide, protein-carbohydrate, protein-protein and cell-biomaterial interactions. Also, in the method for fabricating the bio-silica chip, a probe chip can be selectively immobilized on a silica device chip, which is widely used in biosensors, without a chemical surface treatment process.

  • Publication number: 20090314350
    Abstract: An organic solar cell and a method of manufacturing the same. This invention relates to a method of manufacturing an organic solar cell including forming nano patterns on a photoactive layer using a nanoimprinting process, and applying a cathode electrode material on the photoactive layer having the nano patterns so that the cathode electrode material infiltrates the nano patterns of the photoactive layer, thus increasing electron conductivity and efficiently forming a pathway for the transfer of electrons, and to an organic solar cell manufactured through the method. This method reduces loss of photocurrent occurring as a result of aggregation of an electron acceptor material and improves molecular orientation of an electron donor in the nanoimprinting process to thus increase cell efficiency. Thereby, the organic solar cell having high efficiency is manufactured at low cost through a simple manufacturing process.
