Abstract: We disclose a blockchain e-voting system, where keeping the basic principles of voting does not require trusted-third parties. The system includes at least two vote nodes each having two sets of private and public keys, a voter management node, two smart contract modules, and a blockchain. A voter management node is configured to provide a cryptographic base for public key generation and to pre-register DIDs of vote nodes. A first smart contract module is configured to perform self-identification of vote nodes, encryption of votes, and generation of zero-knowledge proofs for the validity of their results, and to upload all the outputs to a blockchain. For the purpose, a vote node executes the first smart contract module, taking a voting decision, an asserted DID, the two sets of public and private keys as inputs, where one set of keys is for the self-identification, and another set is for the encryption. A second smart contract module is configured to download the votes from the blockchain, check the validity of proofs, tally up the results without decrypting them, and finally upload the results to blockchain.

Abstract: Disclosed are a one-pot biosensor and an immunoassay method using the same. The one-pot biosensor includes a photocatalyst substrate deposited with metal nanoparticles; and a reaction pad which is disposed on an upper surface of the photocatalyst substrate and includes a first binding material-fluorescent material complex specifically binding to a molecule to be detected, and the immunoassay method using the same. The one-pot biosensor may detect a target by once solution injection and has a size enough to be portable. Accordingly, since the one-pot biosensor can detect the target by only once solution injection without a washing step, because of a sensor platform capable of being easily used by an individual other than a diagnostic expert, it is predicted to be positioned as a means capable of confirming the health condition of the individual without seeing the doctor, such as a pregnancy diagnostic kit which has been currently commercialized.

Abstract: A nanofiber membrane includes a polymer nanofiber; and an amphiphilic triblock copolymer bonded to the surface of the polymer nanofiber, the amphiphilic triblock copolymer includes a hydrophobic portion; hydrophilic portions positioned at both ends of the hydrophobic portion; and a low surface energy portion positioned at one end of each of the hydrophilic portions positioned at both ends of the hydrophobic portion, and the hydrophobic portion of the amphiphilic triblock copolymer is bonded to the surface of the polymer nanofiber and the hydrophilic portion and the low surface energy portion are exposed to the outside of the surface of the polymer nanofiber. The membrane simultaneously exhibits hydrophilicity, underwater oleophobicity, and low oil adhesion force, thus has surface segregation properties, and as a result, has an excellent oil permeate flux, exhibits antifouling properties, and can excellently separate oil in water.
